Years ago there was a BR discipline called hunter benchrest and it required a case capacity that was thought to be big enough to deer hunt with( i can't remember how many grains it was). I can remember hearing some of them say when the power charge got above 40 grains that small rifle primers were getting close to being not enough to work properly. The Palma brass was made with a small primer to reduce primer pockets from getting loose too quick, there is more metal left in the case head to resist expansion with a smaller primer than a larger one. Guys reloading magnum guns used to say they got better ES with standard LRP I tried in a 300 RUM and was not too successful till I went back to magnum primers. I wasn't successful with the first magnum primer I tried but soon found single digit ES numbers that I was never close to with LRP. I would try a few LRP cases as experiments and try enough different primers till I could prove it one way or another.
Which brass should I use?
