*As a kid, everytime I shot 50 woodchucks at old fam farms (the area of the one is the Greater Kuduland of groundhogs!!!) I'd stack the empty box(es) on a beam inside the barn. My Dad and his friend Meyer demolished that (c. 1875) barn c. 2005ish and I counted well over 1,000 rds in boxes. I would NOT want to get shot by a .22 WMR and "I've known some" woodchuck descendants "that look at me, like" they owe me a Win or CCI 40 gr JHP. That'd more than "leave a mark!" Now I recall about 4 years as a kid not seeing a single one (but that was the mission imparted upon me by farmers at the time.) I just let them be now if they're not harming anything, but I can be cajoled into going out in the long fields in July or Aug by friends that want to practice with their deer rigs in .257, 6.5 (or even larger.) With my history, I'd test out ALL rifles on woodchucks after sighting-in (but .338 A-Sq, .350 Rem Mag and .375 HH-w/270 gr TSXs for varmints LOL were the largest we ever used for such nonsense.) 'Son took a video of the 375 shots! My seagate backup HD is being restored, and I do have it on a CD somewhere, so I can post if anyone wishes to behold. As i recall, it didn't have the typical effect of the 3,500 fps varmint or mag rifle, but it just flipped them into some kind of irrevocable multiple backflip! SMH GL with the daughter's rig(s)! I have one and she still hunts when not working or taking care of patients, soon to be 2 kids and one soldier! Cannot wait to get the grandkids involved....
