At the minimum many 1/2 moa groups (at least 5 shots) at 100 yards will more or less prove that your rifle/scope mechanics are good.
I respectfully submit no matter how good the ammunition, scope and shooter, the heavy majority of big game rifles for which handloads are being assembled are not capable of repeatedly/reliably producing 1/2 moa five shot groups.
The shooter and the environment are tough to control variables.
I look at OCW,OBT and ES, and rifle/scope mechanics . If these markers are good then the problem lies with the shooter and his/her interpretation of the environment .
Chasing ones tail is counter productive.
