Group size which is it.
Okay I learned along time ago that group size was total distance of bullets apart from eachother from center of bullet hole to center of bullet hole. So if you shot a three round group that cloverleafed then you could actually be under the actual bullet diameter on your group. I see alot of people showing groups on here that claim .3 inch groups or under and one of them is not touching the other two. If they are shooting .308 caliber bullets or bigger it's not possible, they would all have to touch eachother they way I learned to calculate groups.
Anyway I know that the world record 300yd group was .317 of an inch with a M-14 open sights shot at a military match shoot. You know that is somekind of shooting.
So when I say I shot a .5 inch group with my .308 caliber bullet that means I have two on top eachother and one just outside the other two holes.
Is this correct or is there other ways to calculate groups?
thanks

RE: Group size which is it.
eldeguello - I think your calculations are wrong. A 1/2" group can be had with a.224 or a .308 bullet.
.500 - .308 = .192 and .500 - .224 - .276 (so you could have a small space between the bullets)
with a .224 bullet: 1/2 dia + .112 (.112 + .112 + .276= .500)
Just carifying and not being judgemental.
