Browning A-bolt , plastic stock off sand bags , 220 gr. 325 WSM that belonged to a friend , first 2 shots almost touching next 3 opened up to about 6 inches as I began to flinch , danged thing kicks a lot worse than heavy load 30-06 220 gr. out of my model 70, about a week before I got full use of my right shoulder, he never shot it just sold it and as far as I know the next 2 owners were still working on the same box of shells that I opened and not 1 head of game taken , still don't know why it kicked so bad unless ity was a bad batch of factory ammo or the barrel was a little on the tight side but dang it hurt jrh55
