[QUOTE="milo-2, post: 911266, member: 33622"] Ron and I are by no means ballisticians:rolleyes:, nor schooled in how to figure the bc of a bullet. Ron's been crunching numbers since day one, kind of settled on .660. We shot side by side yesterday, good wind, up to 4 moa adj at 1K. Me shooting a 7mm saum, 180 Berger hybrid, he the .296, our wind holds were so comparable shot to shot, impacts on the target were virtually identical. Really can't compare up dopes as I run a 200 yard zero, him, 100. When we left the range yesterday we were thinking it has to in the mid .670 range. After revisiting it last night, with my velocities almost 100fps faster than his, it has to be higher. I have a second saum, with a more comparable velocity rate, we'll test again, but by the weather forecast, it might be a couple weeks:) We'll get some numbers for you, the Redneck way! [/QUOTE]
