The Firing Line Forums - View Single Post - Primer pocket too large in federal brass?

Clark · December 31, 2012, 05:53 AM

I built a rifle in October with a 257 Roberts Ackley Improved chamber and I used Norma 7x57mm Rimmed brass. I necked down and turned the necks. The primer pockets got loose with loads that would have been ok with rimless brass. And there is a lot more brass meat around the pocket in a rimmed case. So Norma sold me dead soft case heads for $1 each.

There is a product, I have not tried it, called a brass saver:

OK, I ordered one.
