I know this is better suited for the gunsmithing forum, but this forum gets more views so figured I'd pick all y'all's brains
The gun: kimber 84L 270
the situation:
Last range outing I had 4 FTF, 2 with factory winchester rounds and 2 with reloaded rounds using CCI primers. If it had only happened with the reloads I would assume it was an issue with primers or primer seating, but since the occurance also happened with factory then I had to begin thinking it could be something with the gun. Also to note these 4 FTF came in less than 20 rds fired, so a pretty high percentage.
I took the bolt apart and inspected the spring and firing pin, did not dissasemble this at all, just took the shroud and firing pin out of the bolt body. There was no oil or grease residue that would indicate the firing pin was getting gummed up or inhibited to move freely
So I had a bit more load testing to do and decided I would get some winchester primers, as I had read that CCI primers tend to be very tough so if I was having an issue with a weak spring a different primer may solve the problem. Well today at the range was even worse. I had loaded 15 rds and had 5 factory loads. Of the 13 relaods that I tried to fire only 4 fired, that's 9 FTF. However all 5 factory loads fired which is curious
I load my primers with the lee auto prime. I have never had an issue in the past and the system is pretty fool proof. upon inspection of the primers you would not be able to distinguish between a reload or factory round based on the primer being seated too deep in. I even had a round that had the primer protruding a little bit and it was a FTF.
So what do you guys think? Is it more likely that I ended up with a terrible batch of winchester primers? Before I take the gun to a smith is there an easy way to check firing pin protrusion/length that it's striking and power?
I will be loading some blanks into another gun to see if the primers fail or fire regularily in it to eliminate if it's problems with the primers. But I won't be able to get to a farm area to fire those off for a little while
