New 24V owner

I have a Savage 24V in .222/20Ga, and have never experienced this problem. Have you had the buttstock off to see if there is anything loose in the barrel break mechanism? Is there a lot of grease on the locking lug in the receiver? Have you taken the barrel off and operated the barrel break lever to observe the movement of the locking lug? Without touching the barrel break lever, with the barrel off, try to push on the locking lug to see how easy it moves. Sounds like something is "un-hitched" back there in the locking mechanism. Hope this helps. Please let us know what the problem was, so if we encounter it, we'll know how to fix it. Thanks and good luck.
