My skills seem to be outgrowing my equipment. I have been using a gun vise, not sure of the make. but it's one of the more popular ones and nothing fancy. I am finding that with a hunting trigger I just can't keep my rifle situated at greater distances, so my groups are opening up exponentially the farther I go. I have pretty much learned everything I know from reading here and other places and I don't have anyone who knows what the hell they're talking about who can teach me- except people here. What do most people do to get an extremely good hold on the target at longer than usual distances- like 500+ yds? I am thinking about using the Harris and sanbagging the rear, but since it's the taller model Harris, I need a pretty big sandbag to bring the barrel up to level with the ground. I would love to hear what most people are doing because when I see pics of some of your groups I am very confused as to how you are getting the hold to shoot sub moa at longer ranges. I can make ragged holes at 100 so I think it's user error that is preventing moa. Do people get a better hold off the bipod/sandbag combination? Should I be shopping around for some kind of gun vise that is superior to the one I have, if so, which one is good?
