Then I start shooting at distance and it seems to work OK and based on just a few years of trying to get extreem accuracy and speed for LRH.
I like the longer range groups to reflect what the gun is capable of, if I shoot 1/2 MOA at 100 yrds I want to see it farther down range. Or MOC at 500yrds, Minute Of Coyote
I would be tweeked if I was shooting a RUM at winmag velocity!!!
HA now your talking Minute of Coyote
It has been a while sence I've shot my rifle and looked at my load data . So i decided to go and see exactly what I was running as far as MV .
AV MV of 2,845
85.5 grains of retumbo
381 yard 3 shot group 3 inches center to center.
This load produced .256 group at 200 yards.
I think I messed up at the 381 yard target one round went just before I was completely ready.
What I don't like about this load is it produced a 63.24 ES and a 33.64 SD and that sucks for way out their.
One question for you guys I know I probably shouldn't have done it this way but I obatined my AV MV by a 3 shot average . Shouldn't I have done it by a 10 shot string wouldn't that be a more consitent way of obtaining an accurate AV ?
