I just bought a 10/22 takedown and from day 1 it has been failing to eject. The bolt almost completely closes but the spent casing gets stuck on its way out. I gave the gun a good cleaning and it has not fixed the problem. I have used many different kinds of ammo that works perfectly on my other one. This particular rifle is just giving me issues for some reason. Anyone ever have any experience with this problem? I'm also using all different kinds of ruger factory mags. Any help would be awesome. Thanks.
