RE: .270 cartridge
A.277 bullet in the right place is strong medicine: A 300 ultra mag in the gut isn't! I have a friend who has a Browning A- Bolt 300 ultra which can't fire a group smaller than 6" at 100 yds over sandbags, but the rifle will do better than 1 moa as I have proven. He just can't handle the blast and recoil, and won't admit it!
