Chronograph Advice

My fun or goal is to see if I can get 5 shots through the same hole , and I have actually,done that 3 times in the past week.
It has been a great accomplishment for me.
I use the chrony to help me get close to the sweet speeds I read about , or see reviews on. If I'm at 5 pellets through the same hole I'm done tuning , and record how I did it by scope adjustments , pellet speed etc. Then start over with a new weight pellet which means resetting everything then go back , and see if I can do it again.
My FX Bobcat & Royale, Evanix Sniper X2, Reximex Throne 2, AirForce Condor and Talons and a couple of my older British rifles will usually drop 3 at 40-45 yards before I pull one. Niksan Ozarks are close.

Haven't let the Max 1 go beyond 25 yards until I get a couple hundred rounds through it. Seems pretty accurate so far.

I just shoot paper recently as I have seen 1squirrel and no raccoon in 8 months at least. The squirrel died.
