We used a MR-52 target scaled down to show 600 yards. My groups were under 2 inch off a bag if I took my time at 200 yards and for 100 yards always under an inch or less. Don't shot a rifle that much. Out of 132,428 rounds loaded about 5,000 rifle rounds the rest pistol. I would rather cast and reload than shoot. If I had to stop casting or reloading never go to the range again. Got the 300 magnum because it was left handed and only cost me 400.00 Ruger 77. The guy running the match told me I could not use cast bullets because I would not hit the targets. So I asked to fire a couple for him to see how they worked. After that he had no problem letting me shoot.
