not sure what you mean, but if you mean go/no-go, I own them for all cal.'s I build, or have ever owned, If you mean the comparitor type, i find them very useful.
Everyone should at least own a go gauge for every rifle they own if they are loading for
them and especally if they are loading hot. (After many high pressure loads are fired
there can be some set back and the go gauge will alert you that this is happening because
head space will increase).
If you have a factory rifle they are handy for checking head space before fire forming and
if it doesent shoot well it can eliminate the head space issue.
If you shoot factory rifles and factory ammo and don't reload you probably don't need one.
They are normally $30.00 to $35.00 dollars and well worth the cost. (Even if you only use it
once or twice).

The recoil surfaces can actually deform (Hammered)and loose several thousandths in length
when the yeald strength of the bolt and reciever is exceeded.
Sometimes a non lapped bolt will gain head space because of the % of contact area is less
than 100%.
I think Fifty driver has seen this more than once Maybe he will chime in and comment on his
experance with this problem.
I am sure that there are more guys that have seen it also with there cannons.
