It might help if you gave a little more info. The velocity would be helpful, as well as the bullet BC, or at least your barrel length. I suspect that you may only know your barrel length. I think CorBon publishes velocities on their boxes?? This would allow someone to plug in some numbers and give you a rough idea. Someone who shoots this bullet would at least need to know your sight height, the height of the cross hairs above center line bore, to give you any meaningful answers. Depending on your sight height, you could be low or HIGH at 100 yards, if by drop you mean point of impact.

The box says 1900 fps, 16" bbl. I will have to measure sight tonite, i am putting a RRA mount on in place of the dot . Thx. I am guessing it is 2 1/2 " or close to it. I will post it on fri. thx for the info and help. W.B.

Big,

Sorry about being so late, but I was gone for a week trying to fling arrows at elk.

Here is the input data:

1900 feet per second
50 yard zero
3.00" centerline scope above bore
ballistic coefficient .200 ( I do not have actual, but they usually run right around this for JHP 300's
300 grain JHP

0: -3.00"
50: 0.00"
100: +0.06"
200: -11.46"
300: -44.45"

Hope this helps, and if you need further figgering, drop me a line.

Craig
