If this question comes to the CBA board for a decision, and it will sooner or later, I will argue against it (at least for our non-military matches) because it adds to the cost of competing and will not make it any easier to recruit new members, thus bad for the CBA.
But if the Board OKs target cameras, I will buy one the next day and then celebrate because it will be an advantage to me personally even if my competition has them.
Being able to see the last bullet hole and be able to go back to the sighter for more information will be an advantage on those days when the usual 30 caliber holes can't be seen, even with the best spotting scope. If this weren't true military shooters with their iron sights and 6X scopes wouldn't bother to bring a spotting scope which they all do.
However, because I have compete in CBA matches with a 222 or 223, some days I can't see the holes at 200 sometimes when my competitors with 30 caliber holes can. Allowing target cameras will eliminate that disadvantage of shooting small calibers and help me win matches against the 30 caliber shooters.
I suspect that when this decision comes to the Board, that the board will leave this decision for military rifle to the Director of Military Rifle since military rifle has its own set of rules.
