It does bring up the question though… at what point does the size of the hole not matter any more? Extensive research seems to show that .40 and .45 have just about the same effectiveness. People justified stepping down to .35-.36 caliber (9mm) because modern hollowpoints could make up the difference, plus lower recoil which does lead to faster followups and perhaps better subsequent shot placement. Bonus in a little more capacity.
Now we’re talking about stepping down -again- to .312, with another added capacity bonus, and roughly the same recoil. But at some point the terminal effectiveness of a hollow point will have to start shrinking just due to the decrease in bore diameter, right?
Looking into my crystal ball, I see many will argue that diameter matters below .355", but ceases to matter above .355". That's with the unexpanded projectile of course. Because we all know it needs to expand to 1.5X (or greater) of the original diameter, which would be.... 0.5325". And Federal only claims the expansion of their 100gr 30SC is 0.530", which is just too small because [insert pseudo science here]. That 0.0025" is absolutely critical to effectively stop an attacker.
Solved it! This cartridge obviously cannot work.
