So I’m guessing you got it set to 95 ip, (7.92fp). I also have a stainless Zytel M77, what I did at the range was to torque-tune the rear screw. The middle one is just snug, (not tight) and it stays that way. The tightness of the rear one is important though.
I started with the rear one snug and shot one, tighten it down a little more and shot again. I could see the group tighten up as I shot. I can’t tell you how many shots it’s gonna take to get there though, I’ve done this to all my M77’s not just the boat paddle and it’s worked for me. They all shoot sub MOA if I do my part.
