I can't remember if I posted this or not.
I bought a used Remmy 700 30/06 this spring for a build,,, 2" of the blue-ing was worn off the crown,,, pretty sure that the barrel was face down on the floor boards of his pick-up truck for alot of years.
I took it to the shooting range after doing a full check-over,,, some times it would group,,, then it would throw out fly-ers...
We checked the rifling and crown as it looked good,,, changed the optic and trigger and it still threw out fly-ers...
Cold,,, hot,,, warm the free floated barrel would punch 2 or 7 tight holes,,, then 2 or 3 off the map... Even my gun-smith friend was scratching his head on this one,,, we fine toothed the rifling 2 more times and found nothing... my motto is pizz-za on it... Ain't no way I'm about to take second best on a hunting rifle with a used barrel,,, and I'm not about to walk around in the wilds with a 20 or 22" pipe... Ha...
So decided to re-barrel the rifle with a wild-cat / Sammy Spec cartridge using the Aught-Six case...
New Jury Pipe,,, zero stress bedding on the factory wood stock,,, we all ready did the new trigger and optic/ rings/ and base,,, we normally do the Pacific Tool and Guage Bolts,,, but with our sinking dollars up here in the North we decided to do the old factory rifle bolt project from the bench rest days to keep them tight in the action...
Mill the back part of the bolt shank down,,, Mill and collar the shank,,, spec it then fit it tight into the action,,, then slowly mill it down to fit snugg and smooth... My friend noticed that the firing pin didn't seem to slide into place very easy,,, so he spun it on the lathe,,, sure enough... We found the probable cause to the fly-ers...
The firing pin was bent between the head that Slams into the inner bolt face and the release drop that the shear of the trigger holds,,, the bend was in the spring area... The firing pin head would sometimes jam inside the inner shank causing a 100.000 thou of a hang-up,,, other times it wouldn't...
Who-da Thunk... LOL...
Problem solved as I ended up with a tack driver,,, if the rifle show signs of fly-ers,,, I'll order a new firing pin,,, so far so good
Problem solving is sometimes things we don't see and over look. My Gunsmith friend had encountered this a few other times in his career,,, its very rare that it happens... Kind of like a refreshing the memory on all of this stuff...
He strengthen out the firing pin,,, polished the inside of the inner bolt shank, then graphite dusted it since we run our firing pins dry with no oil up here in the North...
Lite 3+1 oil if we have to as a alternative """if""" needed when in a pinch... Ha...
Like the old guy said,,, rifles produce fly-ers that are sometimes challanging to track down,,, it takes some insight to find the areas that """could""" cause them...
Happy hunting everyone,,, it show time up here in the North...
