[QUOTE="shortpants, post: 1049173, member: 30564"] Guys I appreciate the responses. I built this gun specifically to be the ultimate 1 rifle for North America out to 1200yds. but know it is plenty capable of hitting rocks out past a mile. I don't want to turn this into a debate over calibers because I"ve already built the rifle so my mind is pretty much made up on that. To clarify my bullet goes subsonic at 1915yds under the conditions experienced during the 1548yd shot. Altitude was around 3000ft. I'm shooting the 215g Berger Hybrid out of a 28'' barrel at 2965fps. G7 B.C. =.356 At 1548yds The bullet was traveling around 1418fps. This rifle is sub 1/2 moa so shooting a rock at 1548yds thats about 3moa tall is not asking to much. The farther you can obtain drop data while still maintaining even 1moa groups is very valuable info for building a true algorithm to match your specific rifle/ammo. I believe I have discovered the root of my problem. I tweaked my B.C. in order to make my calculator match exactly with my spotters calculator. This can work in one set of conditions but cause issues under different conditions. I believe this is at least part of my problem. I'm going to go back out and shoot again with my real B.C. this time and see what happens. Sometimes I just need to vent my issues out to the masses before the lightbulb goes off. I'll keep you guys posted with my results. Thanks for listening! Jason [/QUOTE]
