Took my .300 Win Mag Remington 710 topped with a 4 x 14 buckmaster to the range today to zero it in. I was shooting earlier in the year with match bullets and some spitzers so it wasn't bad on paper already. At 100 yds I was getting one inch groups, or just over, with my new hunting round. This new round I was testing today is a 180 gr Nosler E-Tip sitting on top of Reloader 22. These are handloads. So, as I said I was getting M.O.A. at 100. Back out to 200 yds and I was grouping 8-10 inches. I was shooting off a lead sled, so I was sure not to pull. I did not feel like I was yanking these shots. What gives? There was about a 15 mile tail/cross wid, but I did not think it would affect my group that drastically. Solutions?
