Well for an AR that would be the cci 450 for me, which I do for ARs. For my 22" uintah (bolt) the Fed 205 match is what works best so far.
The fed "regular" primers seem to be on the hotter side of "normal", but they are very consistent at least for me.
So AR, cci 41 or 450 would be my choice.
If someone were to be loading those 80's in a 243 or 6 CM esp with a ball powder, or such with a bigger case, then maybe "magnum" would be the choice, idk. I load mostly 95-100's in my 243 and my 6 CM is w/ 107 smk's, so not a worry for me.
The 6Arc, with a small case, I'd stick with mag's for the AR for the harder cup. for a bolt, whatever shoots better.
