ISSF Rules specify this also. They limit rifle competition to anything smaller than .33 caliber, and score everything with a .30 cal plug, if needed. In their opinion, someone shooting a larger caliber has the advantage of a larger hole, but the disadvantage of greater recoil to disrupt your position.

It's more of a rules thing people get hung up on. It was a thing for paper targets, so it just carried over to e targets, where it really doesn't make sense, even if they were that accurate.

The marvels of modern technology allow us to do away with all this bullet diameter stuff. The only reason that was ever a thing at all was because when you're looking at a hole in a sheet of paper, it's much easier to tell if the edge hits a line than it is to tell if the center hits a line. The whole idea behind the plugs was to even that out and make sure that we're measuring the same for everyone regardless of caliber. With accoustic targets, that's not a concern - the caliber doesn't matter because (setting aside accuracy issues) you're measuring the center of the impact. It really shouldn't even exist as a setting in the software. Clearly, it's confusing to shooters, and it's a pain to deal with at a match.
That's what we do at North State, .224 default. Frankly, in my opinion though, it really doesn't matter. It just makes some shooters feel better knowing that they may get that .042 edge. They may lose by 10 points but they still worry about the .042 edge.

Just a old story before ShotMarker.
Back in the 90's at Red Wing Min. a Nice Guy named Ruddy. Took me for a walk on the Range after a 600 Match.
He asked way are you shooting that Rifle? Your on the 9 ring. He told me I paid for Middle of the Target, you should use it.
If Ruddy was right default Bullet setting would not be a Big Problem ?
Merry Christmas

I'm guessing that you don't believe that GPS satellites that orbit at 10,900 nautical miles are accurate to 18 inches yet somehow they are. I have a shotmarker and have verified my paper to it and I'm happy.
I have done extensive accuracy testing on mine at 100/200/300/600 yards and like you I have found it to be accurate and reliable. I think attention to some details as described in the user manual especially frame rigidity with no frame movement in the wind are important.
Maybe it's the crack.

Just maybe Adam can come up with the Challenge Robot ! Then we will know the True Story?
I have one shoot on them 99% of the time .
Love them .

You know that we have done test from 600 to a 1000yd and the accuracy is an average of .25" with a sd of .25" for about 30 rounds.
No, I did not know that you have done that testing. I did not do any testing at 1000 yards so I would be interested in your results.
Did you document your results? If so I would like to have a copy of the report and any information you have on the details of your testing.
We did the analysis together over emails a few years ago. You should have a copy of the report.
I remember now, I did not recognize your name. Best wishes,
Has anyone had problems with the cables? Looking for a source of reliable cables that can reliably withstand high winds, rain and snow. I think some connectors may be slightly on the small side of tolerance.

Hey Don,
I quoted you just to give the conversation a nudge a different direction. Not disputing your position.
I also have one and use it extensively. On the other hand, I've done the hard work of measuring bullet holes and positions along with taking sample sizes that would make anyone's eyes water.
I agree with Doug on this, the acoustic systems, in their current form, are incapable of providing the accuracy required to fairly and accurately determine the outcome of a match in a reliable way when a horde of elite shooters show up for a match. There is more than enough evidence to support that position when you actually spend some time on it.
While I like the game the way it was, I'd be willing to give up pit pulled targets *if* a level of accuracy could be established that would both fairly and accurately score EACH and EVERY round fired (including misses). That simply is not the case today.
The systems have promise, but need to evolve to add new sensor technologies to reduce or remove the uncertainty associated with the travel of sound through a moving air mass and concurrent bullet arrivals within earshot of the microphones.
Likewise, the national governing body needs to evolve with the integrity to go actually test stuff themselves and create accountability for rules deviations (take a quick look at the rings on your MR-1FC. I'd bet the 5 and 6 rings are the wrong size). Private emails allowing rule deviations without published notification to all competitors are completely unacceptable.
I'm looking for a new game to play. F-class is becoming too broken for me.
what is a "Challenge Robot"?
The only acoustic systems that may be acceptable for national or record-setting matches are the enclosed system such as used by the CMP or HEXA systems. The HEXA system accuracy are 1 to 2mm

I little Robot Man to check shots in the Pit ?
If some real person shooting whats to challenge a Shot.
