[QUOTE="rscott5028, post: 665708, member: 24624"] Yep. Since the weight was stated for each bullet, I didn't get where he wanted it normalized. I also wondered if the MV for the 140 gr .264 was at the high end for most cartridges and the 230 gr .308 might be at the low end. ...such that a big 30 cal would have an even better advantage with respect to drift at ELR. As to your comments about T-Lag being a bigger factor at higher velocities, (if I understood you correctly), I'm presently trying to setup my 300wm with the 230 gr OTM for a 2076 yd shot. In doing so, I was hoping to remain supersonic. My current mild load was only a few hundred fps shy. So, I added that to my MV and reran the numbers. Much to my surprise, +200 fps on the front end doesn't equal +200 fps at 2k yds. Perhaps that illustrates your point? Or, maybe I'm just delerious? -- richard [/QUOTE]
