[QUOTE="Lefty7mmstw, post: 1031700, member: 48043"] A big 7mm like the 7rum can put a 140 with nearly a .500 bc downrange at over 3500 fps or a 120 with about a .400 bc in the 3600+ fps range. The last time I tried 120's in a 7rum they were north of 3900 fps with book loads and a few cracked 4,000 fps... The 7stw will do 3400 fps with a 140 with relative ease too... Range (yards) Velocity (fps) Energy (ft.-lb.) Trajectory (in) MOAWind Drift in Mils --- 225 yard zero w. .480 bc 140 at 3500 fps Muzzle 3500 3808 -1.5 100 3278 3339 1.2 200 3067 29240 .7 300 2867 2554 -3.51 400 2675 2224 -12 500 2491 1929 [B][I][U] -25.3[/U][/I][/B] [/QUOTE]
