Opinions on 40 super?
I was researching a few powerful cartridges for pistols such as the 460 Rowland, and I came across this cartridge. It's a bottleneck 45 case with a 40 bullet, it has the same energy as a 460 but less recoil, it doesn't require a compensator(although it seems to work on the absolute limit of the gun).
I did some math, i think it would be possible to make a weaker version of this cartridge, down to ~700 ft.lbs, same power as a 10mm, but the recoil of a 45, or maybe a hot 9mm, but that's just a theory
