Had an M8 8x36 non ao once, OEM was 300 yds IIRC, normal scopes it's half.

Shooting SMALL tight groups at closer ranges was not it's forte, b/c you could see a little parallax. Royce what scopes are you referring to in the Leupy? Power?

As to how many shots I fire for groups on paper, always found that a rifle that is accurate will fire consistently accurate 3 shot groups that tells me what I want, as Scott says, the first shot is what matters most.

NEVER shot a 3 shot much less 5 shot 'group' on an animal wink

That said, I can fire say 5 3-shot groups allowing cooling, vs. three 5-shot groups during the same time. I like that...also I consider the higher heat of 5 shots in a sporter vs 3 and how that affects throat wear. I don't want to wear more than necessary.

Alan, no doubt, I often pick days that are not only Calm, but Cold/cool as well, feeling it reduces time for bbl cooling, and the bbl does not get as hot as easily in 40 degrees vs say 95.

Very good read indeed on many aspects of accuracy, precision, and testing ideology/methodology. Thanks all.
