[QUOTE="MontanaRifleman, post: 326816, member: 11717"] ronedog, Tank summed it up pretty well. I'll add that the two biggest things in LR shooting besides the obvious accuracy/consistancy, are BC and velocity. That's what gets you farther down range with more enrgy/momentum and bucks wind. But like Tank mentioned, sometimes there are tradeoffs. His report on RL17's temp sensitivity has me a little concerned. We get some extreme swings in temps here in MT which would have an effect on the bullet's performance at longer ranges. RL 22 and 25 usually produce good velocities but they are very temp sensitive. The Hodgdon Etreme powders are less temp sensitive. If you're looking for 1K shooting, you should be striving for sub .5 MOA accuracy. I am finding that my MOA accuracy gets slightly better at 300 and 400 yds than 100yds. You should be testing your accuracy at 300 yds and farther because bullets sometimes take a little while to "go to sleep" which referes to their pitch and yaw. You should be looking for 1" - 1 1/2" groups @ 300 yds and 1 1/2" - 2" groups @ 400 yds. Mark [/QUOTE]
