I've seen alot of good replies. From a bench I like the rifle to be as accurate as possible, most my centerfires are under 1.5" for 3 shots and my Safari Arms .50cal sidelock will do 2.5". After I find the load I am going to shoot I put the paper away and get out claypigeons (4" diameter) and place them at distances up to 200yds(I've gone farther but not an everyday occurance) on gravel banks of the pit I shoot in. I then walk around and shoot them from unknown distances..... if U are real close the exploding sand sometimes shatters the pigeon but u can tell upon closer inspection. If you can hit that clay pigeon than no deer is going to walk away. I have also used cans,2L pop bottles filled w/water and balloons
I don't shoot running game b/c I know my shots won't hit. I have been told that I should get a spare tire and fill the centre w/plywood, roll it down a hill and practice that way. Anyone else have any tips?
