Tool/gauge?

[SDB777]

What tool/gauge is used to measure group size? Does anyone have a link to purchase such a tool/gauge?

Thanks
Scott

SBD,
Charlie Hood, Hood Custom Machine makes a neat Little plastic card to use as an overlay to measure groups.,706)335-8165 Mostly I just use a set of calipers to measure the distance between the two furthest points and subtract the diameter of the bullet used to shoot the group.

Thanks for posting and welcome to the forum....

You drive a 777?
