I wouldn’t shoot 1.25 oz shells in anything less than 7.5 lbs. really bad on wood. I killed several hundred with 1 oz 1165-1200 fps #6s out of a 16ga. Even Godzilla looking fox squirrels with grey faces that were too tuff to eat ( but did anyway). Lol grandfather always gave me he#@ about not shooting those tough a$$ old squirrels.
