I just bought a TC Encore barrel in 454 casual. The barrel is 20" long. I can find lots of ballistics on the round when fired from a 7.5 or 10" barrel but nothing from a 20" Barrel.
How can I find out my FPS and energy at 50, 100, 150 yards. Also, if I zero in a 100 yds, how high or low will I be at 50 or 150 yards.
I have seen some of the ballistic calculaters but I am on a mac and they work on pc's.
I am shooting Winchester 260 gr Ballistic silvertips.
Any help would be appreciated.
