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
Sounds like you have somthing dastardly living in your chamber. Try some of your old ammo and see if it does it to them also. Also visually look at as much of the chamber as you can see. If it is just doing it in one spot on the cartridge there is something catching on the mouth of the cartridge. Try slowly moving the bolt forward with one of the LeverEvolution rounds and see if you can feel where it is picking up that problem.

Check your magazine lips to see if any portion is digging into the round as its fed into the chamber too.
Does it happen if you drop a round into the chamber and try to close the bolt or only when you feed from the magazine?
good day:
it only happens when fed from the magazine.
it looks to me as if the mouth of the cartridge is catching on the leading edge of the chamber at the bottom portion of the case.

If its only happening when fed from the magazine, I would suggest polishing the magazine leading edge with a Dremel to eliminate any burrs or sharp edges. That should eliminate the problem. Check the Numrich web site to see if they have any replacement magazines should the polishing not solve the problem.
You could also open the forward mag lips some to let the cartridge rise a bit sooner.
Opening the feed lips a bit and polishing the radius where the cartridge slides past the feed lips will be your best bet as stated. IIRC, Numrich did have magazines but they're not cheap. Midway USA is another possible source.
there around $40- most of the time
