I have been shooting a 338-416 Rigby since 1996, and I love it. I have taken elk and moose with it. It shoots groups in the .5's off a bench at 100 yards loaded with 230 grain Failsafe, 119 grains of H-870, Federal 215M primers at 3288 fps, using an Oehler chronograph. I am just getting started in the longrange stuff, so can't give you a lot of detail about extended range. The rifle is built on an Enfield action, Lilja #5 30 inch barrel and NightForce scope. Rifle as shown weight 12 pounds.
