[QUOTE="lancetkenyon, post: 2538255, member: 68875"] Have you run the numbers? 169 @ 2778 vs 143 @ 3080? Where you hit 1800fps minimum? For where I elk hunt, 6500' & 30°: 169 @ 810 yds and 1213ft/lbs 143 @ 830yds and 1034ft/lbs I don't think 20 yards makes much of a difference. 143 retains minimum velocity just a hair further, but the 169 has more energy, and more mass/SD to shed and retain. 169 also has 4" less wind drift in a 10mph full value wind at 820 yds. The 143 has WAY less drop at 820 however. 171" (20 MOA) vs 138" (16 MOA) drop. I would say pretty much a toss up at 800 yards. [/QUOTE]
