[QUOTE="MontanaRifleman, post: 316485, member: 11717"] LTLR, A couple of possibilities to consider. Your MV is on the high side for most .338 cartridges shooting a 225 gr bullet. I'm guessing that the testing that led to the published BC was probably out of something like a 338 WM with an MV of less than 2900 fps. Most bullets will exhibit a higher G1 BC at higher velocities and drop off as they slow down. That would be consistant with 300saum's 1200 yd testing with an MV of 3200 showing the lower .550 BC. Also, maybe your chrony is reading a little slow too? Just some thoughts... -MR [/QUOTE]
