I don’t know if this would help you or not. Or if there might be some rule against it in some competitions. It’s called a “phoneskope”.
I have one that I a man still getting used to. So can not say how well it might work.
It is an adapter to mount a smart phone to your spotting or rifle scope that will project the image onto the screen of the phone. The hope was to be able to easily see the smaller bullet holes, or check the target seated without having to actually look through the spotting scope.
It seems like it will work. The problems have been the only time I have tried it at 200 yards was on a new rifle that I was developing a load and trying to get on target.
To see 22 or 25 caliber holes I needed to zoom in on the target with the camera and there is a bit of a learning curve. The more stable the tripod or scope mount, the easier it will be.
With more time, I’m sure that results would improve.
A larger screen might also be helpful, mine is about 4” wide.
Cost is about $75-100.
