[QUOTE="M67, post: 696556, member: 26259"] Alignment I have fired in exess of 2000 rounds @LR in 2012, about 4000 rounds total this far 2012. I logged 24 shooting sessions @ ranges >1km. For my 6.5x55 i use two different profiles (instead of banded BCs, i do use G7 BCs) one is spot on to about 900m and use the Litz automatic BC, from 600-1500m i use a different BC .295 In the 338LM i use .419 in Bulletflight, and auto in Shooter - the goddamned program wont let me see it which is a hindrance... There is full consistency between chronographed (over more than a year) velocities, and reverse-engineered velocities made from drop values. the 6.5x55 barrel has 4200 rds. down it and shows a steady decline in velocity. Using both apps, or my logbook, i would expect to make 1. round hits on any sensible target to at least 1200m, give or take wind. Optics My 6.5x55 and 223 LR rifles both have Vortex Razor HD 5-20x50 scopes, the 338 has a IOR 3.5-18x50 MP8 FFP SH *** scope and my .22LR "silent practice" rifle has a March 3-24x42. None of the scopes has ever given me any issues to click value, repeatabilty or tracking. Original question None of the above has anything to do with the question: [B]Why do the apps give significantly different predictions?[/B] In addition to the things considering when shooting flat (well it must be for [I]total [/I]accuracy, og when the arc of the bullet is high enough, as in artillery proper) is: - gravity acting along bullet path - density change due to different pressure along bullet path - density change due to different temperature along bullet path at least... [B]do the apps consider these things, and others?[/B] K [/QUOTE]
