Bullet B.C.-Help

I am trying to arrive at a b.c. number for a new bullet and I am not sure how to get it to match my drops.

bullet: Matrix .264/ 160gr vld
velocity: 2965fps
station pressure:24.6
temp:38 degrees
sight height:1.9"
drops: 100yds-0

The 100,300,600yd numbers are measured from the center of 3 shot groups shot on one target. The 1030yd number is a measured distance but the impact is close estimate on a rock. It could be a bit off.

If any number crunchers want to give it a go I would appreciate it.

Re: Bullet B.C.-Help

Where did you find 160gr .264 matrix bullets? They only go up to 140gr on their web page.
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
