I'm replacing the old faithful Steyr Scout that I've used as a foxing rifle and centrefire target practice gun for some years - it's still good but is ready for semi-retirement in the hands of a chicken-guard. I want another of the same calibre, and would appreciate advice. The two I'm thinking of are the Blaser R93 or possibly an AR-15 straight-pull, maybe a Southern Gun Company one. The ARs have a 1:8 twist that will handle heavier loads; the Blaser a 1:12. I would also like to have a crack at Practical Rifle. Are the ARs suitable for field use? Would mild embarrassment at ownership - living the dream of every social inadequate who has ever thrapped over a copy of Guns and Ammo - spoil my enjoyment of the rifle?
