Brent, I'm pretty much a newbie to this forum but I have been shooting and scoring targets since 1963 so please don't tell me I don't understand what you are trying to say because I do.
First, I assume that when you say "Crescent Wrench" you mean a scoring plug.
Hello Mr MKnarr
It was me thats used "cresent wrench" a sorta weak attempt at humor.

Having score a lot of high power targets, small bore targets and benchrest targets and trying to measure groups with a calipers I can say from experience that each is almost as subjective as another.
BrentD if i may, is not talking about measuring groups. With Rimfire scoring 1 shot per bull -his suggestion was about measuring distance from the bull, add the distance to get "string". His examples are an overlay of 3 targets for ease of camparison.

My opinion is the plug and 10X eyeloop is less subjective.
Second, How does one make a protest in your world when all the competitor sees is a number?
Third, that is not the way the benchrest game is scored. As has happened in the past, you are always welcome to start your own sport.
Fourth, what happens when the shot is so centered you have no center mark to reference from?
Brent suggested using a template aligned with the rings with a pin prick for center.

Fifth, how come every NRA and Benchrest shooting program I know of goes by score and not string measurement? This is a game shot for score. I can see that string measurements might have some merit IF you were measuring groups but groups are so tight today that your center reference point could be not found with as much accuracy as using a plug for score.
It looks to me like Benchrest groups are a measure of "String". Rimefire uses "score". It took me a little to figure the difference. Rimfire is "scored" by rings and distance from center of the bull. BR has no "BULL" to measure from.

And finally, it seems to me that measuring by string instead of using a plug might take until the middle of the next week after the match is over.
Mr MKnarr in no way am i disrespecting your words, i will never have the experience you have. Probably the word "string" should have never been mentioned in this thread. Brent was referring to a string of numbers.

I mean if you have ever scored a benchrest target, well more than half can be scored by eye, no plug necessary. Some targets don't even require a plug.
Did you mean RIMFIRE target?

As always, just my opinion.
