I had my gunsmith chamber my rifle to 264 win mag. Well he ordered me a barrel that was threaded and chambered. Well all seemed well, I loaded rounds at the standard oal. Shoots ok not great. I figured I would play with some 140 bergers so I grabbed my gauge case and stuck the tool in the gun figued I would see how long I could load them well the chamber is so long that the 140 will fall out of the case before it touches the rifiling???. I have never seen this before. Can somebody enlighten me as to what goin on with my rig.
