Hello All---

Like most I have been lurking for quite some time gathering all the good info I could from a rather enlightened group of people here on RimFireCentral, however recently I have a question of my own that I do not see addressed anywhere.

Recently I was out shooting my old 151 and have a good day at that when I heard a odd noise. I soon found out that my firing pin had broke in two at the secontion where it is cut out for the pin in the bolt. (The most narrow of spots)

I was rather frustrated, however quickly realizing that it most likely was original I quickly calmed. :)

I ordered and recieved a new firing pin to which I promptly installed. Not being a gun smith I was a bit cautious of my efforts, however being a simply firing pin replacement I thought I should be fine.

In fact for some extra security I removed the bullet and powder from a round and simply loaded a primed case to which was promptly stuck by the new pin.

I then headed out to the range to give 'er a good whirl and found things to be going along just fine for the first few rounds. Then i had a jam--- a double feed actually. After clearing that I went on and the same happened a few shots down the road. Finally I was getting to the last 4-5 rounds in the tube when one trigger pull = a double tap. Effectively the rifle shot two rounds automatically, and then stopped. The last two rounds went down range just fine with no jams.

I thought it to be very odd, and rare that the rifle would operate this way so I loaded it again to make sure it could be reproduced. To which I found it can--Simply put the rifle now jams much more often, and almost without fail when getting down to the last 5-6 rounds in the tube fired off a pair instead of a single shot.

I have since taken the rifle apart and thouroughly cleaned it, however the same performance/effect plauges me.

I am currently looking for a smith in the SoCal, Los Angeles area that is familiar with the 151Mb to take a look, however I am simply puzzled how this can be happening as the action of this model rifle is rather straight forward.


This rifle is going into a smith before i take it out again for fear the ATF will have my head if it is thought to be "automatic" due to it's current state.

My questions are:

Has anyone ever experienced this and what was the cause? (Ideas?)

And...

Does anyone know of a smith in my area that has knowledge of these rifles?


Thanks for the help guys and gals!

Dave

I have a 151M that acts about the same. It may have something to do with the cartridge stop that regulates how the cartridges are fed out of the tube. I don't really know enough to give sound advice but I think if you would search the forum you would find something on this. It may be blasphemy to say this but It could be that this rifle has a natural tendency to do this.
Afret20-

Thanks for the reply, however I have shot 1000s of .22lr rounds through the rifle and never had it "double" on me. I also am used to "frequent" jams, or stovepipes but not at this rate....

I should also note that I tried 5 different makes of .22lr---everything from Velocitors/Varmit loads to normal Remmington HP, Blazer, CCI....

Thank you both for the very informative posts. It really does make sense now...I guess I simply didn't "want" it to be the pin.

I did try cycling the rifle fully loaded manually via the bolt. After I checked each round for any kind of mark--to which it had none.

It may be binding---Ill give it a polish and see, but if that doesn't do the trick then off to the smith it goes.


Anyone out there know of any in my area, or a good directory to use?

Dave
