[QUOTE="Shawn Carlock, post: 37349, member: 4"] G Grouper, I haven't shot the mile but am setting up to do it soon with my 338 Edge. I have shot 1560 yards. I shoot the 300 gr SMK @ 2900+. The biggest biggest group problem I have seen is accountable to velocity spreads. 20 FPS from one shot to another should change your vertical impact bout 70 inches or so. The ogive could be accountable for a certain ammount of velocity spread. My 338 EDGE/300 SMK/H1000) load runs an extreame velocity spread of 8 or 10 fps if I do my part loading. I can consistantly hit 14-16" rock I shoot at, at 1560 yards in good conditions. I would take a hard look at my ES and try to get it trimmed down to single digits even if you have to drop a little velocity. Shawn [/QUOTE]
