Stephen, those groups were done with the factory stock ,O-rings and a little bit of bedding work. The groups could be repeated but I still would get an occasional flyer usually high. I never would let the barrel get hot, 6 shots and let it cool for a few minutes while I checked the groups. I had close to 400 rds through the barrel at that time. I always test fire from a bench and use shooting bags. My 100 yd targets would still open up to 2-3'' so I have added a boyds stock. The O-rings will not work on boyds stock so I came up with something new which has worked even better. I have posted all of my work on rimfire central.com in the Bmag Accuracy topic.
50yds / 3 shots.



100 yds.
