    Does anybody have a ballistics program? I am going to shoot in a D-Day battle rifle match with a .303 (7.7X56R) Enfield. Will be shooting 300,200 and 100yds. I am using factory 180gr ptbt, .328B.C. Advertised vel is 2421fps.. With a 200yd zero where will i be at 100 and 300? thanks, jim

      Thanks, the program works good. I need to be 3" high at 100 and will be 12" low at 300. jim

        jhjimbo... that is exactly what I get with my ballistics calculator. Note that at 300 yards, your energy has dropped to about 1100 ft/lbs which is fine for target shooting but marginal for deer shooting.

          I would disagree Dakota.

          A 44 magnum 240 Gr bullet @ 1400 fps has about 1100 ft/lbs at the muzzle. My concern would be if the bullet would expand sufficiently, but penetration should not be an issue.

            That heat Saturday was unpleasant, for sure. I can't complain much, though. While you were busting your rear, and Pighunter was no doubt recuperating...

            Finally got caught up at work. Three months and it’s full bore again. They’d better find some decent help or I’m retiring early.
