Getting above 2300 fps with a 400 grain projectile in a 20" .416 is very impressive. Might penetrate better than a 500 grain .450 at around 2150 fps. I'm thinking 9 1/2 pounds including scope would be about perfect for me if it were 416 Ruger. A Boyd's laminated classic style with cheekpiece weighs 45 oz, extended magazine to hold 4 rounds adds maybe 2 oz and perhaps an extra 40 thou" over the factory Ruger .416 barrel, at 22" should do it.
