[QUOTE="NZ Longranger, post: 502478, member: 14"] LTLR, We pretty much agree, within splitting hairs distance anyway. Load, Man, this is the problem, not comparing apples with apples again. You're quoting factory BC's measured (or estimated ) by all different means. The only comparable BC results we have are Bryan Litz's, and they are the only ones I'm going to use in a debate. Whether you agree or disagree with Bryan's BC on an individual bullet, the comparison is accurate. As I've said several times now, I'm only interested in debating with facts! The 240/250 SMK's BC's run .647 G1 BC. You can't drive them fast enough to equal the ballistics of the 210 Berger/208 A-Max. We don't have Litz measured BC's for the 225gn Hornady yet unfortunately, so I can't say much about them. Only that Hornady rate their 208 A-Max at .648 but the Litz measured is .633, so I expect the .67 to come down a bit. But anyway at the .67 you're quoting, they certainly won't beat a 7mm 180gn Hybrid ballistically. You have quoted the BC for the 180gn Target, not the new 180gn Hybrid. Berger haven't updated their website for a while unfortunately, but they've been available and I've been shooting them for some time now and they have featured on this forum several times. Their Litz measured BC is .674 G1 and .345 G7, and it says this on the box. From my extended range testing this is right on. I'm sorry but your 300 shooting the 225's (which may well be the highest BC 30 cal bullet available) at 2825 fps even at your claimed BC of .67, doesn't beat the 7mm RM's 2900fps or thereabouts velocity with the 180gn Hybrid. I'm out of this thread now unless there is some new accurate information of interest. I'm not going to continually correct misinformation like yours - it will just end up in a slanging match!
