Poor little gophers. I’m going to tell my girlfriends in PITA about you. When they show up at your door please feed them some gopher stew and explain that it’s made with tofu instead of gopher. That way they will go to PITA hell.
Crowmags worked great in my .22 Condor at low power. High velocity and they go crazy.
Try scrubing the barrel with JB Bore paste. The Eun Jins Work great in my .25cal.
The bore paste will increase velocity and help accuarcy. Breaks in the barrel so eun jins should fit fine.
I know it sounds funny but it works.
It works with other rifles as well, I had my Sumatra new. I tested the velocity before the bore paste. Scrubbed the barrel and velocity increased by 90fps.
