Im glad you mentioned that and not me Semi Nice shooting and it looks like your ready for opening day.
Im a pyro rs shooter also, I had times where I had groups like this and upped the pyro to 90grs and the groups tightened, added a tooch more and they got a little tighter. Sometimes I refuse to blame the shooting on me untill I try all options.
I know you have way more experience than I do with that type of MLer, just thought I'd add my 2 cents.
Good Luck and Tag a Big One.
