Firing pin problem?

[fabsroman]

Took the 10/22 to the range today to try out the new Green Mountain barrel and ended up getting frustrated and disgusted. The firing pin barely struck the rims, and it was very rare for me to have two shots fired in a row. For the most part, I was firing one round out of 5 cycles. I would pull the trigger, and if it didn't go pop, I would pull the bolt back and try again. I hate this range because I have to shoot their ammo and never know what the deal is. At first, I was using some Blazer crapola, but after several unfired rounds, where I could see the primer rim being dented, I switched to CCI standard velocity rounds. I think that was even worse.

Could it be that I put the barrel on wrong? I only had to tighten two allen head screws and I tightened them down pretty good. What else could it be? The gun sits in the safe a lot with the bolt open, but would this affect the firing pin spring? The gun is about 7 years old and it has hardly been shot. Should I dry fire it before putting it back?

What should I do to try and fix this problem? I was thinking about ordering a new CNC machined bolt and firing pin spring from Volquartsen, but I really do not want to spend $200 for this. However, would installing a new bolt and firing pin on the gun fix the problem? Is there anything else I can do that would be cheaper and effective?
