I have a beautiful new Ruger bolt action .22 that takes the Ruger 10 rnd. rotary mags. At the range, I had a problem with extraction with the Aguila .22 ammo. About every 3rd or 4th shot, the spent casing wouldn't extract and I had to use the tip of my knife to get it out. I tried Federal and CCI .22 and had no extraction problems. Has anyone else encountered this?
