The magic number that's been thrown around North America for ages is 1000ft/lbs of energy, not something I've come up with on my own, unlike the numbers you've been throwing around.
"the ol' boys" rule of thumb of 1000ft/lbs of energy.
Mic drop Thank you

What numbers have I thrown around? Besides my opinion on minimum caliber?
But the 1000 ft/lbs of energy is a pretty fair rule of thumb
