Yowza! My rifle used to win about every match it shot in, or at least it came across the finish line swappin' paint for first place. How many gear gremlins do we have to chase to keep our groups tight and well behaved on target?
I noticed that my little 6BR wasn't keeping the the five shot groups as tight as it used to. I also noticed I wasn't winning small group anymore either. Grrrrrrr...
After evaluating a few things, I determined that with 1,700 rounds on the barrel, within a two-year period, it may be time to change the firing pin spring.
The rifle is just under 17 pounds, uses a Nesika J action, and sports a Brux 1/8 barrel. And the rifle can race with the best of 'em.
We'll, with the bolt removed, and in the disassembly fixture, I loosened the first set screw, and removed it. This is when I noticed the cocking sear was loose and no longer tight against the firing pin with the 2nd set screw. Grrrrrrr....
I went ahead and changed the $15 firing pin spring that I purchased from Jim Borden. Now, with the new spring and tightened set screws, the rifle should be able to start bringing home some blue ribbons once again, as well as some green ones
Folks, do what I did before you need to do it. Go give your rifle a once over inspection. And be sure to check your bolt assembly throughout. This way, you can stay on center and keep those groups tightened-up.
