Got a 30-06 and I want to be able to reach out and touch something 500-800 yards an need to know what grain round would work for this. I am on a budget my kids cost me a bunch of money so less money for higher quality ammo. I was thinking a 150 grain to keep my rounds trajectory a little flatter and keep the velocity up. Am I right or wrong? Any suggestions? Also the rifle is a Remington 710 so I was a little iffy about putting a 200-220 grain round in?
