Need Muzzle Vel.

If it is factory ammo that would help.

Jimmy Boss

Yes Sir, it is factory ammo.(Lake City) They say about 3150fps. I would like to know est bullet drop. Thanks

JB this should be pretty close.
55gr-3100fps. (energy ft-lbs) (100/935)(200/715)(300/539)(400/398)(500/281)
(bullet trajectory-in.) zeroed @ 200yds (100/-1.5)(200/0)(300/-7.4)(400/-22.9)(500/-49.1)
Hope this is helpful, have fun[:D]

I thought that for accurate info you would need barrel length as well?

john kerry, out to prove he's got nothing to prove.

Nope, barrel length changes muzzle velocity, but the initial velocity is whats important.

The only two things that are of importance are the muzzle velocity and BC (Ballistic coefficient).

You know how fast its going at the start and the BC tells you how fast the air slows it down as it travels, thats all you need to know. Punch those 2 numbers into a ballistics program with your zero distance and they'll pop out results.

Windage is a factor as well, but not one you use for zeroing and drop.

Jimmy Boss

Thanks for the help and info.

Welcome on board.

If you have the Muzzle velocity and go to a reloading book ballistic charts you are going to get real close.

Good luck.
