We got our RMC 3.5" brass 12ga cases. These are turned
cases using shotgun primer. They have nice thick base,
and a good radius in the corner. Got a Brenekke OK 437 gr
slug to 2800 fps, a 540gr Hammerhead slug to 2450. got 600gr
Dixie to 2300, the 715gr RG jacketed to 2130, and a 1400gr
Darwin to 1400 plus. Tested in NEF. Shot one case 15 times
and still going strong, tight primer, with loads running about
20- 24,000 psi.I have pics of cases soon, and we also will
test these brass ones and 3.5" plastic in 12ga Encore
