I have a custom 1911 that is set up to shoot 45 Super, really just very hot 45 acp. I have been doing this forever using 185 SWC-BB-HP-NLG bullets that I coat with Hi-Tek. I have used a specific recipe just about forever with very good results. My 1911 longslide is set up from top to bottom to deal deal with it.
Today I was reading and found that a version of the 45 Super was being rolled with a 45 acp case with a small primer pocket using small rifle primers.
I never thought about doing this. I guess that would give more brass around the that area of the case and the rifle primer would give more pop than a small pistol primer.
I just happened to have most of a 5 gallon bucket full of 45 acp small primer brass that my wife was given for me. It has been sitting untouched because of fear of getting it mixed up and causing a catastrophic accident in my Dillon 650.
I seated some small rifle primers in a few. I thought they would be too high. They weren't. They were normal depth and looked/felt fine. I then thought they would be too hard to fire reliably. Nope. The titanium firing pin popped each one, no problem.
Bottom line. Do you think this whole idea of using small rifle primered 45 acp case is:
A) A good idea.
B) Pointless, it doesn't matter one way or the other.
C) Dangerous you moron!
There's no doubt that the pop a small rifle primer puts out is much more than a small pistol primer and maybe more than magnum large pistol primers.
It's an interesting idea...
