[QUOTE="pressman, post: 310782, member: 10980"] i just spent one week in Sheridan Wyoming doing some long range shooting. i live in southern Indiana and i was wondering a few things. i have a custom 260 i zeroed it here in indiana 750 above sea level at 100 yards. my light loads were a light 2706fps with 139 gr Lapua bullets i was having trouble with a drop chart being correct when i arrived. the altitude their was 4230 above sea level and i was just wondering was my speed of my bullet different their than here in indiana? out their this was my actual moa on my scope that i dialed. 500-8.5 moa 600=12.5 moa 700= 16.5 moa 800= 19 moa 1200=39moa 1400-=49.5 moa My exball was really close but i was wanting to build a drop chart for here in indiana to mount inside my scope covers but i could not get it to match by putting in the data verses what i was actually getting in the field. any help would be great. also while i was their i was hitting a 3' foot target at 1975 yards ( with a 50 cal.) we had a great week.
