.410 brass shells: make your own!

OK, so I owe you guys some pictures but wanted to start a discussion on reloading brass .410 shotgun shells, mainly in the form of fire-forming .303 british or .444 marlin cases. For you folks using the magtech brass feel free to add to this as well.

There are a couple other odd-ball rounds out there that convert to .410 size shells but .444 marlin and .303 british are the two that seem to be used the most.

In my experimenting so far, .303 takes several shots to fire-form and the rim thickness is too much. .444 marlin fits perfect and is already a straight wall case, measuring roughly 2 1/4"

I've had decent results so far using Circle-Fly's wads/overshot cards although i've tried using my own wads as well. Greased Felt is great, milk cartons make great wads/powder seals also... just time consuming.

if you make your own wads you will need a 7/16" hole punch, I bought an entire set at Harbor freight for cheap. honestly though, as cheap as they are, I am leaning towards just buying my wads from circle fly (out of Pennsylvania, my home state) from now on. it's only about $7-8 per 1000ct, that's a lot of work with a punch...

basically, the best results so far have been outta my .444 marlins using 8.0gns of Herco, circle fly wads/powder seals and an overshot card from index card stock sealed with elmer's glue. I plan on using water-glass as soon as I get my hand on some but glue works in a pinch.

you can easily make OOO buckshot loads (3 pellets, 4 max) and 1/2oz shot loads.

The whole point of this (besides a reloading addiction) is to retain adequate amounts of .410 shells as the plastic hulls wear out quickly and are extremely expensive. Brass is obviously more expensive initially but lasts virtually forever.

for those who don't want to read my longwinded post, here's the skinny:

.444 Marlin brass
Large Pistol Primers (I've been using Winchester)
Herco (started with 8.0 gns)
circle-fly wads (powder seal x 1, fiber wad x 1)
overshot card (made from thinnest material possible besides paper, using manila/index card stock right now)
Elmer's glue or waterglass

without the seal on top, you won't develop any pressure unless you use black powder. the glue/waterglass creates enough backpressure to simulate a factory crimp and develp some useable velocities.

Anyway, I have tons more info to post but I will stop here, let's hear your thoughts!

Problem with waterglass is, like any other adhesive, it congeals when exposed to air. So, you open your jar (I have a quart), pour some into a container and close up your jar, hoping that enough oxygen did not get in there to cause the surface to set up. Unless you are doing bunches and bunches at one time, whatever you have poured off in your small container has congealed before you get your third batch of shells loaded.

Elmers works the best, for me.

I was trying 30/40 Krag, as I have lots of that. Rim is too thick. Must take the thickness off the front of the rim. Much easier to remove it from the rear, but that makes the primer pocket shorter. Taking it off from the front, without cutting a hole in the side of the brass, is tricky, and a PITA. So I gave up and bought the Mag-tech stuff.

Load 12 gauge, 16 gauge and 410s. The 410s are the easiest. 44/40 shell holder for priming. Pulled a half-ounce load out of Hodgdons manual. Powder, overpowder wad, felt wad, shot, overshot card, glue. I tried putting a small amount of crimp on it, just to make them feed into the gun easier. Shot the crimp off. The three I crimped are now a 16th of an inch shorter than my others. Oh well. Single shot and SxS, so I don't need that curved in front to feed from a magazine.

I've been thinking of making "slug" loads. 180 grain 40 S&W bullet. Twice as heavy as a regular 410 slug, but still lighter than normal shot loads, so should not have a problem with safe powder charges. Probably won't be very accurate, but for up close and personal it might make an impression.

I also use Circle Fly wads.

Before I got to the middle of your first post I was thinking "somebody has been reading the endtimedreport". When you fire-formed the 303 brass did you fill the case with cream o wheat? It's easier to just buy the brass.

yeah, I tried the cream of wheat trick with the .303's and it's a PITA and not really worth it unless you have a bunch already. I will be buying some magtech to experiment with shortly as well...

I prefere the .444 marlin, perfect fit so far in my O/U .410 (Verona LX501) and just haven't gotten around to ordering Magtech brass yet, they are a little bit longer than the .444's.

good to know about the waterglass, these are the things I want to cover, thanks for posting that up! I think just about anything you use will cause some major fouling in the bore and elmer's is cheap/easy to get. I will try the smallest container of waterglass and see how many times I can open/re-open before it becomes useless.

been busy lately and haven't messed much with this project but will keep updating this thread with anything new as I discover it/find it. Need to get some photos up too....

thanks fellas, keep her going!

Something I've thought about, but haven't tried. A syringe. Suck up a syringe-full and close the jar back. When you go to seal your shell, just squirt some down into it. If you keep the level all the way up to the spout, only that part could gel. The rest, inside the syringe, should stay liquid. Maybe.

you do owe me some pics aa, I wanna see.... Love brass shotshells, they just look cooler being put down the tubes of a double SXS than the 'spaceage' plastic shells do;)

bumping my old thread, haven't done much with this lately and even backtracked a bit by ordering two cases of remington STS .410's when Brownells opened their ammo/free shipping deal.

I have several people on the lookout for more .444 marlin shells to add to my collection, I don't think I will waste my time with .303's although it still is a viable option for anyone who already has a bunch. the .444's fit perfect and are already straightwalled and take a large pistol primer in the large rifle pocket.

I'm thinking about just sticking with black powder/elmer's glue for this project at least for now and see how many rounds of skeet I can do between cleanings, my guess is not too many.

My personal laptop crashed, just bought a refurbished desktop so should be able to get some photos posted up here shortly of my progress.

I also have a chrony now so I will run some smokeless and black powder loads thru to see how much difference there is.

want to get back to this, already burned up a case of factory ammo and been messing around with slugs and buckshot for the last year or so, skeet range should open back up here shortly so I can pull out the over/under .410 and get busy!

made some from 303 yea its a pia easy trick to anneal; leave primer in and stick case in your lead pot the primer keeps the lead out of the inside of the case. gives a nice even heat to your brass. tip 2, use a roll of cork from ace hardware to cut for your over powder and over shot cards. cut with a gasket punch or an old 45 apc brass drill hole in the primer pocket to allow you to push them out after cutting.. tip 3, seal them with wax either bees wax or paraffin from the canning aisle of grocery store or hardware.

You're annealing the ENTIRE CASE?

this thread got me to thinking.

ok.. so if you can reshape 303 or similar brass to 410 use. I guess then a couple questions.

are you usign a shotgun press to reload.. or using a large single stage press and special dies ( ie.. the rcbs rock chucker will accept the larger dies with rmeoval of the /8 bushing ).

and lastly.

any problem with ignition using the lr primer? vs a shotgun round using a shotgun primer?

using a magnum lrp? or?

might be nice to laod up some brass shells for my circuit judge.. and be able to do it on my regular press .. as I'm not looking into doing regular shotshell relaoding with an MEC or anything..

thanks

I'm really amazed at these folks that use .444 brass. Maybe it works because of the slanted edge of the rim.

http://stevespages.com/jpg/cd444marlin.jpg

But 303 Brit and 30/40 Krag are supposed to work. Notice they have almost the same diameter and thickness of rim as the .444. But then, the 30/40 has a slanted rim edge.

http://stevespages.com/jpg/cd303british.jpg

http://stevespages.com/jpg/cd3040krag.jpg

I have never tried 444 brass, but I have tried 303 and 30/40 in 4 different shotguns, and since three of 'em were SxS, that means seven different barrels. None of the guns would close. Thinning the top of the head, which would be easier, would make the primer pocket shallower. So you'd have to thin the rim from the backside. I tried it. Pain in the butt. That's why I was so happy that the actual 410 brass became available.

My brass cases, in 12 gauge, 16 gauge and 410, all use LP primers. Pistol, not rifle, and there is plenty of fire there to set the powder off.

use large pistol primers is my recommendation instead of large rifle. I think a shotgun primer is just the equivalent of a large pistol primer anyway, it's just set in a different/larger case.

Still haven't ordered any water-glass to use yet, this project will get underway down the road, I promise! Just busy lately with little time to reload. (relatively that is)

OK, took some photos of the (much ignored) project. some .303 cases that are almost done, a few are ready to go but most need one more firing with COW (cream of wheat).

Here's the best pic of fire-forming the 303 british shells although they do work out OK, the rims are very tight and some will not close in my gun. (Verona LX501 O/U)

.444 works out much better I think, all close in the gun and no fire forming needed. Magtech brass even better, more room.

cream of wheat! tastes good and works great for working those british cases. Black powder gives the best results, less need to get a good seal.

you can see the results of using black powder and not cleaning the shells right away though; bad corrosion on a few from sitting un-disturbed for too long!

Loading 410 Shot Shells Using 444 Marlin Brass ( by Jim H.)
First, I want to acknowledge the article written by Woody, and copied below, which was most helpful in my starting of this endeavor. Quote,
"For reference, the base diameter of factory .410's is 0.469", and the rim diameter is 0.524". .444 Marlin cases are straight walled and can be used as .410 brass without the need for fireforming, but have the penalty of a 2.162" case length. The base diameter of the .444 Marlin is 0.469", whereas the .303 British has a base diameter of 0.458". The rim diameter is smaller with the .444 Marlin - 0.514" instead of the 0530" rim diameter of the .303 British - so it is theoretically possible that a really loose extractor might not catch the rim. The 9.3 x 74R European brass has a base diameter of 0.465", a rim diameter of 0.524, and an overall length of 3.47". The rim thickness (headspace) of the 9.3 x 74R, however, can be a tight fit in minimum .410 bore shotgun chambers, and may need to be thinned before use. Obviously we're only talking a few hundreds or thousands of an inch differences here, but it is a complication not taken with abandon.
FWIW - Loading .444's for the .410

Assuming we're using fired cases, check to see if they'll fit in the shotgun. If not they'll need resizing at some point.

De-prime any way you can, even to using a homemade punch from a 16d nail.
Re-prime using an appropriate shell holder and large rifle (or pistol) primers.

Add appropriate powder charge for ½ oz. .410 load. Top powder charge with overpowder wad seated firmly against the powder with a 3/8" dowel. I cut my own wads from cardboard boxes ranging from primer boxes to cereal boxes using a homemade cutter. I then add one or two more cardboard wads lubed with bullet lube and top with a styrofoam filler wad cut from a meat packing tray. Again, seat wads firmly. Note, no seating die used. With a little finger finesse, the wads can be inserted individually and run down inside the case with the dowel.

Add shot and top with an overshot wad, again, homemade from card stock. The overshot wad can be sealed with most anything from Elmer's glue to waterglass (the old way). In addition, if desired, a slight bevel can be added to everything by running the loaded shell into a .308 size die until it contacts the shoulder. This also resizes the case sufficiently that it always fits in my .410's.

I wrote this up for another forum. Maybe it'll help you. Regards, Woody"

I have perfected the use of 444 Marlin Brass in the loading of 410 Shot Shells in the following ways.

I have two over/under 410 shotguns. Both shotguns require sanding of the heads on the 444 Marlin brass to permit complete and proper breach closing. I use a 2" belt sander (be sure to use the portion of the moving belt that has the backup plate support below in order to obtain flat sanding of the head) and a 15/32 bit and drill to spin the brass on the moving sand belt. I use a "stop" on the sander that is set to about 1/8" above the moving belt which keeps the spinning shell from "tracking" off, or all over, the moving belt. Also, use a glove to remove the sanded shell from the bit, it will be extremely hot after only a 1 second sanding. Carefully remove all of the embossed brass head lettering and try in your gun to gauge the amount of any extra brass needed to be removed to properly close the breach. Some loose breached guns my not need this sanding to properly close. Check by closing the gun with no 444 Marlin shells in the chambers as well as with shells. The opening tang on the gun should be identical with both checks. If not, continue to sand the shell head. See left photo below, also note the "SHIP" metal plate clamped to the sander table to get above the backup plate for the flat sanding of the spinning head.

I now use a 444 Marlin de-priming size die (Lee 444 Marlin die set) to de-prime and re-prime the used shells ( see 9:00 and 12:00 positions dies on the right photo above, one is without a de-priming pin the other is with a de-priming pin). Re-prime with either Large Pistol (preferred) or Large Rifle primers.
I then use a Lee Powder measure set to drop 12.0 to 12.2 grains of Hodgen LiL Gun Powder into the brass, followed by Claybuster or Remington 410 red plastic wads for ½ oz.s of shot (see right photo below). All shells loaded with powder and topped with these wads (for 2 1/2" shells). Then the wads are pressed down firmly with a 5/16"x 6" stove bolt. See the upper right photo above, the ¼ x 6" stove bolt has large washers bolted to the head and is shown out of focus at the top of the photo.

I then fill the shells with ½ to 9/16 oz. of shot using an old MEC loader with the bar drilled out to give slightly more than ½ oz. to properly fill the shell. See Left photo above.
I now use a homemade punch (pictured below left) on my drill press to cut out plastic overshot wads (using old gal plastic milk or water jugs) that barely (.450" diameter size or less) can be inserted in the mouth of the shell over #6 to #9 shot. Cut wads are pictured below right.

I now use a bullet seating die that I have modified using an old 308 bullet seating die, and an 18 mm nut that I have ground down (outside diameter)to just fit inside the die head and made to a conical shaped hole (smallest diameter about 13/32"or slightly less) using tapered drill bits and tapered grinding stones. I insert the modified tapered hole nut in the top of the bullet seating die, which has been further modified using a ÂĽ" stove bolt (with head ground to about 5/16" diameter so as to pass through the 18 mm modified tapered hole nut) in order to seat the plastic overshot wad to the proper depth. This ÂĽ" stove bolt is threaded through the die cap and held in place by a locking nut. Thus, when I seat the plastic overshot wad I also taper the cartridge mouth (with the same taper as the modified 18 mm nut) so the shot cannot come out. I can screw the ÂĽ" bolt in the top of the die cap (the cap that holds the 18 mm nut modified in place inside the die) to put pressure on the overshot wad inside the tapered shell to get the proper depth of wad. The proper position of the overshot wad is sitting on the shot just below where the taper begins. See 6:00 position Left Photo below. Written by Jim H. on Jan.20,2013.

[Loading 410 Shot Shells Using 45 Colt Pistol Brass (by Jim H.)]

Please read " Loading 410 Shot Shells Using 444 Marlin Brass " (by Jim H.) above before reading this article. Most of the techniques are similar.
The same procedure as above for the 444 Marlin brass is used for the 45 Colt brass in sanding off the markings on the head of the brass in order to have the breach on the gun properly close .
Also, use 45 Colt dies to resize the brass and deprime the spent shell.
I use 11.8 to 12.0 grains of Hodgon LiL Gun powder. I then top it with one of my plastic milk jug wads that is slightly larger in diameter than my overshot wads to obtain a snug fit when pressed over the powder (better gas seal). I then use my old MEC loader with a powder hole that has been drilled out to properly fill the brass with sufficient shot to leave just enough space for another overshot wad ( slightly smaller in diameter that the over powder wad) and leaving enough remaining length to make my taper crimp. See the lower right picture below, the loaded shell lying flat is a 45Colt with #9 shot.
I have perfected the plastic milk carton die cutter for 410 wads and have them for sale for $29.95 plus S.H by calling (970-384-2513) and asking for Jim Hickson. It can be used for both wads, over powder wad (slightly larger) and over shot wad ( slightly smaller for easy insertion.
