[QUOTE="Brent, post: 2010, member: 99"] Dave, how close can you get with that method? The veocity I used was 2750 not 2700, the temp was only +20F, BP was 29.53 at 0' elevation and a BC of .462 so I screwed it all up that time. A couple things I noticed when changing the temp was from +20 to +70, the 1480 yd zero moved to 1580 yds at 65moa and 1480 was down to 58.6moa, That's ALOT! Then when I changed the velocity to 2700, down from 2750 the zero moved from 1580 to 1545 yds with the 1580 at 67.7moa now. Just thought this was interesting at this distance. I've never shot that far and haven't looked at the effects at this range much either, they are very dramatic indeed. Any time a spotter could be fired and seen hit it would make a huge difference obviously. The swingset isn't a bad Idea, now where's my old one? Do you think the Kestrel 4000 is worth the $$$. They have them in Cabelas and look pretty sweet but they aren't cheap. [ 05-21-2002: Message edited by: Brent ] [/QUOTE]
