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.
