The blond stock in the gun cabinet is my CVA .58 mountain rifle. I bought it assembled yet unfinished still in the white. It shoots PRB well with 90 grains.

I love my CVA Frontier .50 and loved my previous one as well. However, I want to check if you CVA owners know to keep an eye out for the fault that caused me several negligent discharges?

There is no safety alert system in muzzleloading so I just raise it when I see CVAs discussed.

The fault is caused by firmly tightening the tang bolt. It compresses the very small area of wood supporting the front of the trigger plate. Eventually the trigger blade stops the sear from fully engaging the tumbler notches. BANG!

I solved that problem by inletting and glass bedding fresh wood into the trigger mortise and changing the attachment of the tang bolt from the trigger group to a blind nut in the lock mortise. I put a Davis trigger in place of the stock CVA model and had to modify the mortise and attaching of the trigger anyway. Haven't had any more trigger problems since the mods.

Good work. I inletted more wood for support. But then someone told me he set a copper tube into the stock for the bolt to pass through, that absolutely stopped the trigger plate compressing any wood; I think that would be easier than what I did.

So you actually pillared it, that's a smart fix. :thumbsup: Got pictures?

Pictures of my fix

It was fellow member Necchi who used the tube pillar, and he noted the Mountain Rifle was particularly subject to it.

my hawken and mountain pistol all have bedded tangs/trigger housings. I wont leave them factory in that area since i prefer larger loads.
