Loaded some 30 super carry

Finally got around to loading up some test rounds for 30 super carry.

There is woefully little published data for this still very new cartridge.

Used titegroup 90gr data. Loaded with some hard 93 gr projectiles I use for 327 mag/32 HR mag.

Charge range data was 3-4 gr for 90gr jhc bullets. ( 100gr jhc was 3 - 3.6gr ).

So I decided to load up a few at 3 and a few at 3.4. I never get good results on semi auto at minimum loads.. But 3 on a 93 is technically a hair above that min data... Then again..im running lead not jacketed..albiet hard lead that has done fine in a 327 fed mag.. Which is the rimmed brother to 30 super carry, pressure wise..

Velocity should be in the 1100-1200 fps range.

We will see....

I might have to break down and buy jwords for this thing if I can't figure out happy lead data. So..hoping test goes good for cycling slide..AND not leading.
Feed should be ok. The RN profile seems to like the feed ramp just fine..and I have the taper crimp seemingly perfect using the barrel as a plunk tester.

Hopefully will get out tomorrow after lunch to test.

Almost forgot the pics. Here are some next to a jfn factory.

Ps.. Forgot to mention... The hodgdon data called for small rifle primers... And that's what I used. Hope they fire! 馃槈

Cool! Who makes dies for that cartridge?
Lee at least.. I didn't check past that once I found the 4 die set. One thing I was disappointed on.. Lee always gives you a small block of load data with their die sets.. this die set came with -0- load data.

PS... I gave in and ordered some 100gr JHC projectiles from Graff's last night so that I could dupe factory loads if nothing else. Not a fan of jacketed anymore.. but ya do what ya gotta do...
Range report:

Ok..as expected..the 3gr ones either stove piped or failed to extract. I pretty much knew this but wanted to see it.

3.4gr functioned correctly, although magazine was not always holding slide open..meaning 3.4 was right on the hairy edge of short stroking. I'll up to 3.5 or 3.6 next time. Noticed the recoil on my mid grade loads feels way less than factory..maybe half or 2/3s. Brass is ejecting and piling up 4' away not 6'. Lead slides easier down the pipe than copper..so less pressure was expected..so no surprise there.

Small rifle primers were no problem at all either. No light strikes or failure to fire.

Now that I have a targeted load that works ( 3.4-3.6gr ) I'm going to wait till my hornady 100gr jhc come in and see how well they feed before I decide to do a bulk run of either.

All in all a good day.

No leading noticed..but I'm getting ready to clean the gun and will double check. Probably process my brass again... Be ready for the jhc when they land.

Post cleaning report:
1st dry patch on a nylon bristle brush picked up some black soot..2nd was clean. Sent a very mildly lubed patch up and worked it..came out clean..followed by another dry patch that brought out the faintest bit of oil from the lubed patch. Dry bore inspected with bore light.. Yielded mirror bright like it left the factory. No copper or lead fouling..crisp cut rifling..no smears...good to go.

So far she has had a couple box and a half of factory fmj and my lead reloads thru her so I take that as a good sign.

Action was cleaned..but left cloth white... I think the chamber mouth lead before rifling was the only source of soot..which is what I expected/hoped for for this delayed locked breach design.

Pretty happy over all.

On the plus side too..the cases fit my rcbs uni-jaw hand prime tool. It states 32 cal is minimum..but I find it to be hit or miss on 32acp..not enough of a rim and/or extractor groove . ( fine on 32hr and 327 too because of the real rims ).

Processed the 31 cases I used today..they are sized and primed..waiting for charge and projectiles...

I can't remember what you bought. Was it the EZ. Not sure if anyone else has chambered this round yet. Sounds good so far.

I didn't like the ez. Don't like grip safeties. I ended up with a plus.

Gun shoots good too. It's my first S&W semi auto. Didn't know what to expect. So far so good..except the magazine release button spring was stuck when I got it. Had to insert and drop the mag about 40 times till it suddenly broke loose and started working.

I will say that the barrel looks better than many commercial guns I have seen that have rough finish.

What's wrong with jacketed?

You have to buy them usually. :)

Cast I can make easily...but lacking the multitude of swage setup $$gear$$ to make bullet jackets.. I hafta buy them..and jacketed projectiles can be pricey. 23-50c each, not counting shipping.. depending.. Vs cast lead that costs me about 1.55$ per 7000 grains..meaning..an average 158gr 38spl projectile costs me about 3.5c to make.. Call it 4 cents when lubed. I just checked powder Valley.. 158gr fmjfn 38/357 would be 28 c each..or 35c shipped.

I'll take 4c over 35c any day! :)
