I have one of those ballistic matched calibrated recital optics... calibrated for 62 grain green tip (M 855) out of a 14.5" barrel.

How can I get a trajectory match for a heaver projectile out of a 16" barrel?

I need some ballistic computer or program that lets the user "compare" different loads and different barrels with out dumping data. Any one know of something like that?

Not a fan of BDC reticles but you should be fairly close between a 14.5" and 16" barrel.
