I had a Hopkins/Allen .36 underhammer I built, it was one accurate little muzzleloader.. Head shot a bunch of squirrels with it anywhere from 10-45 yards and killed a groundhog at 75 yds with a ball thru both ears..
I did cheat and mount a scope on it, sure was a fun little gun.. A friend wanted it more then me though.
Yours looks a tad heavy to squirrel hunt with:)
