I'm shooting a lot of PMC Bronze and Silver Bear .308 ammo to nail my scope dope and prepare for hunting season in the Fall. But I can't find the BC of the bullets anywhere, of course, nor could I find the velocity of the Silver Bear. So I made a first pass at the tables using an online calculator and the bolded info for each cartridge. Could someone take a second to look at my BC and velocities to see if I'm even close? I don't want to go out and burn up ammo without some valid starting point. I took the PMC velocity and trajectory from their site and backed into a BC. For the Silver Bear SP I'm pulling it from my butt.
PMC Bronze 147gr FMJBT BC = .401 Velocity 2780fps
Silver Bear 140gr SP BC = .343 Velocity 2650
I'm using this data to calc my trajectories and come-ups and windage clocks as a starting point. But bullet data on the cheap stuff is hard to come by. Any help at all appreciated.
