[QUOTE="Frogman77, post: 286009, member: 15339"] just to verify, i went out to shoot again, and with a 100 yard zero i needed 5 moa elevation at 200 yards and at 330 yards between 19.5 and 20.5 moa depending on the temp and baro pressure (weather was changing while I was shooting) with that info, BC at .123 and my MV measured avergage 2600 fps ( It's possible the chrony was reading fast) the trajectory doesn't match up with my software or the published charts. to match my trajectory and actual bullet drop from 25 yards to 330 yards I need to input MV of 2500fps, bc .106, scope height of 1.8" first day shooting: temp 60F Baro 30.13 RH 35% second day shooting: temp 45F Baro 29.75 Rh 60% it still kicks up some dirt at 330 yards but not a whole lot. I would say I'd be confident out to 200 yards shooting a critter. Wind drift and energy beyond that gets a little iffy, more of a shooter problem than anything :D [/QUOTE]
