That last shot can be tuff. It's the Bench Rest shooter's bane. Your 2 oz trigger seems to become much heavier for that shot.

Really nice group.Are you using handloads ???
That's no fun when that happens, I shot an almost identical group at 300m on the weekend...four rounds into .335 then opened to an inch and and quarter with the fifth, was a second past when I should have taken another breath and refocused. Good shooting though, what rifle/combo are you using?
