Ok I’ve had this particular bfr in .500 jrh since 2016. It is one of my favorite guns And been used a lot. I have never had one single issue. I got it out to shoot recently and it’s out of no where started misfiring. Very very faint firing pin strikes. Action feels the same when I cocktail the hammer but on the trigger pull after the hammer has dropped I can feel the trigger bounce forward significantly to reset which is something I don’t think I have felt before. Other than that I can feel no difference in the gun at all. I’m looking for any suggestions before I send it back to mri hoping to avoid the hefty shipping charge they fed ex. thanks for any help

Dang spell check... assuming you're not really "cocktailing" the hammer  not sure what you're using as a lube... but I'd try soaking it down with gun scrubber or Kroil, & see if that frees things up to fire correctly again... if it fixes the problem, perhaps find a different lube ( in my experience, stainless guns do need lube ) if it still has the same issue, it's possible one of your springs got damaged under recoil or??? |

Hmmnnn.. gun is not new, broken in nicely it seems. You can over lube the firing pin and almost a suction thing slowing the pin. The lube can get thicker, crusty too. No BFR's here, don't know of quirks possible. Pull the grip panels and see if a spring is catching or binding ?

Don't own any BFRs or Rugers with transfer bars but Bula's thoughts on the firing pin got me thinking. If you take out the cylinder, then push down on the hammer with trigger pulled is there plenty of movement and springiness in the firing pin? If the firing pin's already in a mostly-forward position when struck, maybe it doesn't have enough momentum to pop the primer. Hope you find an easy answer!

Thanks to all reply’s so far. Honestly about the lube I haven’t cleaned the gun in some time. Usually I shoot 20-30 rounds and put away. I did take the grip panels off and check the main spring and trigger spring both looked fine and in the correct position. I have thought maybe it was some kind of transfer bar interference but just a thought. With no rounds in the cylinder I dry fired and can see the firing pin pop out correctly so I know it’s coming out but no idea on strength. After work I will give it a thorough cleaning and try to test it with a few rounds. Just really odd because I was shooting it no issues put it away after a shooting session get it out two weeks later and it’s misfiring. No malfunction of any kind prior to that. Dang spell check cocking not cocktailing  |

Well unfortunately after a thorough cleaning and lube still having misfires. I actually couldn’t get it to fire at all and the firing pin indentation is barely visible on the primer. it definitely feels like it’s the trigger reset something in there is hanging up and sticking.

First thing I would do is pull the cylinder and put the base pin back in. Cock and lower the hammer, keeping the trigger pulled to check for firing pin protrusion. If it's protruding enough to ignite the primer, then we'll go from there.

I’ve been comparing it to my other bfr and it appears to work the same in both. |

I’ve tested my ammo in two other .500jrh one a magnum research and it works perfectly. Something is definitely odd about the trigger reset on the misfiring bfr and sometimes it gets stuck back and a small touch of the hammer resets the trigger |

I've not had my BFR apart as far as some of my Rugers... thinking I remember reading somewhere about a few things that can effect strength of the hammer fall, or the transfer bar... one being, that the cylinder pin is fully seated, & the other slips my mind, may have been one of the small springs under the grip frame... perhaps one is bound up???

I'd simply replace the hammer spring and trigger spring. Both are very simple jobs. |

I’ve looked around and can’t seem to find any for sale. by hammer spring I assume your talking main spring and the trigger return spring for trigger? |

PM me you address and I'll just ship you a set. |
