The newer Mag Tech brass is to hard for rifle shells unless you anneal it about 3/4 of the way down.

With the RMC hulls you can use any straight wall data and 209 primers. I have them in 10 and 16 ga Great hulls.

I have 12g brass shells from Mag-Tech for black powder loads. Got them from BP. I got the brass shell reloading kit from RMC. They have 2 kits, 1 is for their brass, the other is for the foreign (Mag-Tech) brass that uses pistol primers instead of 209s.
