Hi, All!

I just received a CVA Mountain Rifle in the mail that I purchased from a member here on the forum.

I took it out this morning to shoot it and maybe test some loads. I found two problems immediately.

1) it only fires the cap about every third pull of the trigger. The trigger is very smooth, by the way, and consistent.

2) the hammer bounces back to half cock every time it does fire.

I know the number one cause is an eroded nipple, but I only have Musket caps, so I put a brand new nipple on it before I took it out.

I also used 50 grains of 2f with a .490 ball to start.

I thought I read somewhere (cannot find the article) that CVA locks have weak springs. What do I need to do to fix this?
 
Sounds like the main spring is weak. Replacements are available for about $10.
