good day all:
i have a old m340 in 30-30 win.
i thought i would try some hornady lever-evolution ammo in it.
when i tried to chamber a round i found it very difficult to push the bolt forward and close it.
so i ejected the first round and tried another,same thing.
after inspecting the ejected rounds i found that the neck of the case had been slightly peeled back in the same way and the same spot on both cartridges.
could it be the crimp?

any ideas,anyone?

thanks Z
