The critical element in loading for long range accuracy is standard deviation of muzzle velocity. If you roll your own, the easiest way to monitor SD -- and the best way to QC your loads -- is to chronograph them. So owning a chrono is about accuracy. And success, provided you define 'success' as small groups at long range. I shoot over a chrono almost every time I shoot at paper, not out of curiosity, but to QC my work by monitoring my loads' SDs.
Exactly......
THANKS JWP for going to the trouble of limiting XLs quote......
so I didn't have to......
I do agree in GENERAl. However I've observed 'exceptions to the rule' a little more often than I expected.
I look for low SD and ES BUT I've also had 'better than average' groups from loads with higher SD-ES. Curious to me, but have been unable to explain to my own satisfaction how that happens.
I would be surprised it you or others have not experienced the same.
OTOH I have no place to hunt extreme ranges. 400yds is about maximum area for seeing and shooting. Therefore I've been satisfied with loads from 1/2-1" groups (outside-outside) not center-center. I'm sure y'all understand that diff.
On another subject, I rarely find myself on the same page as Mr Redgwell.
