So. I'm a muzzleloader hunter. If my rifle has a sight height of .85 inches. and groups at 25yards are 1.5 inches above 0 and groups at 50 yards are 2.5 inches above 0. The bullet i'm using has a ballistic coefficient of .205. The bullet weight is 240 grains. Is it possible to calculate this with only 2 points of impact? What is the feet per second?

2. Relevant equations

I have no clue

3. The attempt at a solution

I was plugging numbers into a ballistic calculator and couldn't get a good result.

This information is important because a fps that is too high will lead to poor bullet performance on the target.
