So I'm working on batch loading some 357 mag rounds, and came across some very tight primer pockets. I noticed a couple shells took a lot more pressure to seat the primer. One even had a small amount of shaved metal from the primer. The primer pocket on a few of these have no chamfer around the edge, they are straight walled. This is the best pic I could get of it, the one on the bottom right is normal the two on left are the tight ones. No problems that I remember depriming them. Any ideas, there isnt' many, should I just toss them?

I found out the hard way that Fed. .45acp brass use's a diffrent size than, Win.,or harnady Ect..
Might be the same thing. Fed. takes small pistol brass for the 45acp while the others take large.

Use a flat head screw driver that will fit in the primer pockets and give them a quick scrape and you will be set to go. I have a specific screw driver just for that job. To heck with brushes.

For chamfering primer pockets (and removing military crimp/stake marks too), I just use my case mouth chamfer/deburr tool.

I've got some SB 9mm brass here that has the same style pockets. Very little chamfer and they are a bit tighter than the normal WW white box brass that I usually have laying around. Haven't had any problems with getting new primers in other than feel.

S&B is very tight. Almost like it is crimped. I don't have any S&B 357, but I have a lot of their 38s. So the first time I get S&B brass, of any caliber, I run it through the primer-pocket-swager. Solves the problem.

I have found the same thing with CCI Blazer Brass, 45 ACP. No crimp that I can see, but the pocket is very tight. Primer-pocket-swager makes 'em perfect.

It's an extra step, but it's only one time, and they are fine brass cases.

I toss S&B brass for this reason and a few others; I stumbled across some 223 brass last night that had such little internal case capacity when I dropped 25gr Varget it spilled over! Usually for me when something goes wrong on the progressive it turns out to be S&B brass.

Must be nice to have so much brass you can throw it out. I've probably got 15 or 20 thousand 38 cases, in one place or another, and I still save S&B brass. I remember, back when I was starting out, and was trying to reuse EC43 steel 45 cases, 'cause I only had about 100 brass ones.

Ya, brass is like gold to a re loader. When I go to the desert to shoot picking up brass is part of the trip. Now when the grand kids or the wife go they automatically know to be looking every where they step and it is amazing how quick the kids and my wife begin identifying the head stamp on the brass. Now we even pick up the .22 because it packs tighter in a 5 gallon bucket. The vrass that I can't use goes to the recycle and I get about 2 bags of brass for one bucket but with the .22's in there it begins getting very heavy. I am thinking this time I might get 1/3 more for a bucket.

It takes me about 6 months to collect a bucket full of brass (provided I am shooting regularly) because I do it a little at a time. The jewel about it is when you are always looking you will end up finding the good stuff. I can't count how many times I have went out and literally picked up 100+ pieces of once fired brass that someone just chucked aside and it primo nice 45 auto, or 44 mag, or 357 mag. I just recycled about 1000 rounds (same lot of brass that was starting to split and I lost track of how many times they had been reloaded) of .357 brass last year and I believe I am still sitting on thousands more of once fired brass still .357.

yep.. correct tool for correct job.

primer pocket cleaner, brush or blade style.

reamer for crimped pockets.

flash hole cleaner/true-er for mal formed flash holes or ones with debri or burs

pocket true-er to make sure pocket is cut to correct depth and diameter.

same tools are usefull for working on primers that were sealed primers with that red stuff..e tc..

You rock guys. It would have killed me to toss them out. I hate tossing brass. I'll run my chamfer tool on it.

I also go brass hunting when I hit the range. I sort it all out. I don't shoot it now, but I might someday:D It all gets run through my cleaner and then sorted.
