Was trying to shoot up the remnants of old reloads to reduce clutter and get some new loads going ran into a problem that was new to me. In all instances these batches had been fired in the same rifles previously about a year ago. Yesterday the same ammo would not chamber satisfactorily in these two lever action rifles, a well worn Winchester 71 (348 Winchester) cast bullet,and Winchester 94 (375Winchester) jacketed bullet.In both instances a taper crimp had been applied . The ammo has spent some time riding around in my truck but never exposed to high heat. I've measured a few of the rounds and there is no change in OAL.
Any ideas as to what is happening here?.
