My .22 T1X, or more specifically a few of it's magazines, are having some feeding issues.
When fully loaded (or almost fully loaded) the nose of the cartridges sometimes do not come up to the proper feeding angle. When closing the bolt the bullet hits just below the chamber opening and the bolt can not be closed.
It looks like this:
Attached FileThe top round in the left magazine is feeding normally. The right one is not. To get the rounds feeding again I usually tap it on the stock of the rifle. If tapped gently you can see the nose of the cartridge rise in small increments. If I give it a good whack it pops right up into place.
FWIW I am using CCI Standard Velocity almost exclusively and probably have about 3000 rounds through the rifle. Not all the mags do this and cleaning them didn't help. I have heard other people say their mags let the cartridge tip up too much (90°ish) and block the bolt from closing in a near vertical position.
Any ideas?
