Just purchased a Krebs Custom AK-74K. The barrel length is shorter than normal. With the muzzle
brake permanently attached it is 16.25 inches. I estimate the barrel to have a length of 14.5 inches.

I have done a search and found ballistic data on the normal length barrels, but not 14.5 inch. Is there a formula I can use to get accurate data for my shorter barrel?

I found my info here:
