Took my son out today to fire his new Savage MkII after mounting it in the SSS stock. Every type of ammo we tried ejected flawlessly except for the Wolf Match Target and Wolf Match Extra . Each and every Wolf round had to be manually extracted with a pocket knife. The shame is that if it was any other ammo we would not have cared, but the Match Target was scary accurate. We were shooting 100 yds with a bipod on a wobbly wooden bench and our best group was 5 shots that measured 0.8 inches. Any ideas?
