Out thinning the groundhogs for soy bean farming friend this morning. Two down so far and I've located a few more for the afternoon. Shooting my Rem. 700 VSSF in 22-250. Shooting the Sierra 53 gr. HP Match bullets with a heavy load of Win. 748. Prime medicine for the pasture poodles. I've killed hundreds of groundhogs in my 45+ years of shooting them but I had a new first this morning. When I shot the first one this morning, he dropped at the shot but then he squealed 5 or six times just like a dying rabbit. Sounded just like a jack rabbit. Then he died. It surprised me so much that I started looking for a rabbit in the shrapnel area behind the groundhog. Anyone else ever heard one squeal?
