Trivia question for single shot shooters

I am not sure what the real question is here. Hunting and noise? I put a tissue in the tin. Bench and finding the pellets? I will set the needed ones out. Close to count needed? I sort so a new tin is a essentially a new "lot". I shoot 10 and 25 bull targets. At 30 I would shoot the 10 bull. At 30 with a 25 bull it depends on if is a settled run, I would shoot the 25. IF I have to get close with a need to so more than a test for sighter through the run, tune for the next lot and use the 30 another time.
