The Precision rimfire thread

[rambo-6mmrem]

[QUOTE=HJA8;1228766]I measure that way because we do not always use the same thickness of paper/cardboard for targets. Bullet hole dia. can vary widely depending on the target material. Many on these forums seem to use 220 but I have seen holes as small as 190 - Does make some groups look "smaller" than others if you're using the larger dia. Lots of groups we shoot with rim fires are ragged holes and measuring center to center is not easy at times. I prefer to measure the bullet hole dia., set the calipers to zero at that value, then measure group OD. We shoot only for our own pleasure so not splitting hairs like many do in competition.[QUOTE]

Fair enough

I think consistently is the name of the game
Dosn’t really matter how you do it as long as every target is measured the same

Have noticed quite a bit of Difference in hole size on the targets I have been measuring for the forum Challenge
I am measuring Digitally with on target software I leave the hole size set exactly the same for every target
And just Center over the holes as best I can
Measures center to Center
I spend alot of time processing the targets and making sure that i set up the hole markers to the best of my ability
I feel that people have spent time and money entering so the least I can do is score the targets as consistently as possible
