RE: Muzzy 90gr 4 blade grouped 4in below points 2day??
I had the same problem. Mine 100 gr. Muzzys were shooting high. I spent 5 days trying to fix it. I think I have now but my arms are soo tired i need to rest them. I was getting an occasional flyer. If you do try to tune them and you get aggravated just walk away to cool down. I made that mistake which took me soo long.
