Bullet holes. Interpretation???

Clay I'm going with target backer.
I already know you can tune, and I know you know what you is doing.
So my conclusion is space/ gap between target and backer, and or previous holes in backer causing irrattic tears in target.
 
If you want to get a better look at the holes, turn the targets over, gently push the petals down and scotch tape them. They will look different when you turn the target back over. The group size will be easier to measure also.
^^^^^ This. IME regardless if the backer is intact and target is flat against it, by doing the above you can tell any yaw by how the actual bullet hole centers in the blackened outer ring. A clean backer just makes it a lot easier. Usually with custom BR bullets any yaw evident shows with-in the same group or target (if Score)........that is all record shots will appear similar provided one hit the same condition. Shoot the same load later or in different conditions and they usually show different- if not -you have a wide tune window and might just "shoot through" conditions.
 
"Dusty is steering you right. A well-tuned rifle will make small holes with clean edges. When you see ragged edges and paper tears around a bullet hole, the gun needs work.

You can get tricked when the bullet holes start looking like a needle went through the paper because the gun is too hot and getting ready to throw a shot. It’s a fine line between the gun drilling and being too hot."

These were shot on the reverse side of an official NBRSA score target with the bulls made with a rubber stamp I purchased from Sinclair International. The target was stapled to a fresh clean sheet of OSB.

Bret, thanks for the vote of confidence. At 600 yards I do a lot better than this point blank game.
This is not as easy as one might think....... "It's only 100 yards, how tough could it be". That statement is a load of bull squirt!
What I am saying is, I suck at short range BR.
I can give folks a good run for their money at 600, and I can do OK at a grand, but at 100/200, I am only a participant.

^^^^^^^^
Especially that last sentence.

For us that shoot 6PPC’s in the upper load window, you have to be watchful of this. Often, when it decides to throw a shot, it is really bad. Agg killing bad.

Pat Byrne, one of the best Benchrest Shooters I have ever known, once told me if he ever shot a “zero”, he would think about backing it down a tenth or so, because it was probably getting ready to blow up.

I don't go with the "Backing" theories, in our benchrest matches, the target is slid into a frame, there isn't anything behind the paper for maybe 3/4 of an inch before there is a sheet of some kind of backing such as sheet rubber or something else black. We get small round holes when the gun is in tune and big oblong holes when it's not. Pay attention to what Bart says and Jack's vid.
 
Does anyone have a link that shows single separated shots (up close) with an explanation of what each bullet was doing? In other words, shot one, the gun was out of tune. You can tell this because... Shot two - the gun was almost in tune because... Shot three, the gun was perfectly in tune. You can tell this from... This would be very helpful. Thank you in advance.
