Colt Combat Commander in 45 ACP on a mulie? 5' is perfect range.
22LR on geese? Head shots only.
The red mist from a 22-250 on ground squirrels used to make my ex queasy.
375 H&H on jackrabbits? Looks like science class.
30-30 in wild boar? No? How about right smack in the forehead from 15' away? Messy.
7X57 on bobcats? Really makes their eyes bug out if you hit them in the ear.
I think maybe the 8mm Rem Mag on a feral cat was inappropriate, but I'm not sure, couldn't find enough to check.
Never try to educate someone who resists knowledge at all costs.
But what do I know?
