I put a new hammer spring on my 30 30 contender and took it to the range today. I am still getting light strikes and misfires. I tried several different factory loads and had misfires with all of them. I shot 49 times and had I think six misfires. They would fire on the second try. The strikes that caused the misfires were very light just a very small dent more like a pointed scratch.

When I got home I tried swapping barrels with my 223 contender. When I put the 30 30 barrel on the 223 frame it would not lock up. It just falls open if you just move the gun hand.

What is that about and what should I do next. I really like the gun but can not live with that many misfires.
