Wow 900ft/lbs at 500 yds.. My factory .204 remington 40 grains are only in the neighborhood of 325ft/lbs at 500yds, Heck my 22-250 with a 50 grain bullet isnt doing anything close to that, You must be handloading some pretty hot stuff, If not what brand of off the shelf ammo are you shooting? I too would LOVE 900ft/lbs of energy at 500yds. out of my 204. or even my 22-250 for that matter.
