[QUOTE="BallisticsGuy, post: 1322315, member: 96226"] Sure enough. For the Raufoss: 60f @ 27inHg (also experimented down to 15inHg) 58% RH, 671gn, .581bc G1(just what I found online, so this was a matter of some question for me) 100m zero 2900fps 3500m POI (I didn't break down and do 3450 because I do this in excel and I'm lazy too) If I drop your BC in I get very similar numbers. Had that BC been one I'd found, I'd have used it. The drop numbers I got were disregarded because they were starting to hit 400mrad, then 5xx, then >1400 and remaining velocity went below 300fps. For the A-Max I used 2650fps, 1.05BC, I increased the drag decay coefficient (see Pejsa model and Mayewski number stuff, uggh level math) to deal with the BC being over 1.0, and used the same atmospherics as above and got 84.47 drop (a subsonic value which I'm skeptical of anyway) and 7.4mrad of 10mph wind plus a huge amount of horizontal coriolis and spin drift (combined they're 8mrad more of windage). So far I've had exactly 2 discussions where anyone bothered to do some numbers, so thanks Theis. The BC info for the Mk211 does change things. I need to play with that a bit to comment but I'm at work and need to jump off for a minute. I'll jump back in as soon as I have a chance as your data deserves a proper look for sure. [/QUOTE]
