Good morning. I'm new to the thread in search of help. I have a Ulti-mag that is somewhere around 15 years old. It's seen a LOT of use. Last year I started having problems with the occasional misfire where the pin would strike the primer but the shell didn't fire. I tried new shells, different brands, same result. The problem has progressed to the point that it will rarely fire a shell at all. I saw an old post by darcerly0810 on April 12, 2012 on the exact same problem I'm having but I did not see any post on resolution to his problem. The following is what I've done so far:
1) Complete disassembly of the gun including the bolt, clean, reassemble, same problem.
2) I Had the gun and trigger assembly ultrasonically cleaned, same problem.
3) Replaced the firing pin and firing pin spring, same problem.
If I jam the forearm forward to put a new shell in as hard as you possible can, it seems to fire every time. But, when I cycle through under normal, reasonable pressure, it will not fire.
Any thoughts? Is replacing the entire trigger assembly next?
Thanks!
Aaron
