Question about firing pins... - 09/23/09 03:55 PM
I posted a few weeks back about my new CG Bonehill Challenge that I picked up... It's a peach of a gun and I killed several doves with it last weekend during the opening day hunt in the South zone of Texas. I am having one little issue with it though...
To refresh everyone, it's a 12 gauge, modern steel gun, 30" barrels that are in proof for 2.75" Nitro shells. I was shooting Winchester factory light 1 oz loads at about 1100 FPS. What is happening is it seems the firing pins are sticking in the primers. It takes a pretty good deal of force to break the action after firing and the pins leave scrapes on the primers from being dragged across them. (I didn't fire it much this year because of that. It can't be good for them.)
Now, I found this gun on an online auction, bought it, and received it. It is in almost dead mint condition. There are still damascening marks on the face of the chambers, there aren't even safe dings in the finish. It is definately all factory too. It has not been refinished. All I can figure is that this was perhaps a display gun somewhere, or someone who didn't like double guns was given/won this gun and it sat in a safe for 70 years. (The best estimate I can come up with is that this is a pre-war gun, probably 1939, but I'm not positive. I can explain how I got to that conclusion if you'd like.)
Is it possible that the firing pin springs are just still very strong from not being used? The pin indents in the primers aren't abnormally deep, but nevertheless, the pins are sticking in the primers.
Did this particular gun have rebounding pins? Are the rebound springs worn out perhaps? Or does this A&D boxlock just retract the pins as the springs are cocked upon opening?
Needs some help here fellas...
