If you find rifles that shoot small groups interesting maybe you might like to look at this video by Rick Casegrande. He is testing a March 1x-10x Hunting scope on a 416 Rigby that is loaded up very hard. 7,100 foot/lbs of energy here. This is a serious recoiling rifle. Take a look at these groups. You will be surprised I guarantee it.
