I’d want something stronger than all but the most upper end ‘pellet rifles’ for coons. With those high $$ guns people have shot pigs & deer, though not the norm.
Even a regular 22 is barely enough with shots at more than arms length(trapping). I’m referring to 40 yard ‘body shots’.
If needing to limit noise for trapping, I’d look to those quiet type, 20 grain loadings.
For normal hunting, the 17 HMR, 22 mag, & at times a shotgun works well.
