New use of lee app primer swager

[Tomme boy]

I have a bunch of 350 legend brass that has loose primer pockets from the factory loading the brass that was too long causing high pressures. Well it expanded the primer pockets.

At first I tried staking the pocket like LC does on some of the 556 brass with 4 punch marks. That did not work well. So started thinking on how else to do it. I was looking at the factory way pockets were crimped. Then I thought about using the large primer pocket swage pin to swage the pocket just slightly to tighten it up.

Well it works. I made a go type pin to use to see how tight it was. So I swaged each piece till the pin I made will not insert into the hole. There seemed to be a big variance between cases. You had to turn the depth pin on the top die about 3/4 of a turn from one case to another. It works perfect. Now I am able to save the 200 pieces of brass I was going throw away. I am going to use these for lite lead loads only.

Necessity, is the mother of invention.

Huh, gives you a lot of faith in factory loadings...

well the factory and the makers didn't really agree on how things should be shaped or sized.
you see that same thing with the 300 BO.
the factories make one spec of ammo and the various makers out there make about 6 different throats and about 3-4 different neck diameters in their chambers.
makes for some fun if you measure a big one, then buy a small one.

It's sad about both chamberings. Robert Silvers worked hard to standardize the Blackout to ensure its success and longevity. We see the same dimensional mess with the Socom, but mainly because Tromix won't release the drawings and companies copying the chambering are reverse-engineering the reamers. Arne Brennan has an open offer to manufacturers on his 45 Raptor that anyone can produce rifles or barrels on the condition that they involve him to ensure accurate production tolerances.
