How do you measure a group size correctly ? Do you measure the distance from centre to centre of the bullet holes or from the edges and detract the calibre size ?
Either one will give you the same measurement, (if you mean the outside edges and subtract)..or just measure the inside edge to the outside edge of the fartherest holes...
Unless I'm shooting in competition, I don't worry about it...I can eyball them to see if they are within what I expect them to be.

Using the 2 holes with the greatest distance you can do any one of the following and it will give you the same number
1. Center to center
2. Outer edges subtracting bullet diameter
3. Inner edge to outer edge
It makes no difference as any groups reported to the internet are 1/2".....always!!!!
Ideally we measure the two most distant holes center to center using (hopefully) a dial caliper.......but it really don't matter as no matter what it measures...it's 1/2"...unless you're shooting 200 yards and then it's 3/4"

It is funny how every gun out there shoots less than MOA, and if it doesn't it has to be the gun and not the shooter flinching. We have some that will cut a hole out and others that shoot around 2" at 100 yards. Though all of them are more than accurate enough for hunting.

Vapodog,
You need to get a new gun if all you can get is .5. There aint a deer in the world that's gonna die unless you can shoot .25
Have you measured to see if the hole is the same diameter as your bullet? Often, it is not so subtracting the bullet diameter may be shorting yourself.
