Jonathan Browning Mountain Rifle question

[Willy]

I remember losing sleep wanting a JB mountain rifle back when they were being made. Settled for a used T/C Hawken, then a Renegade, and never had the JB.

Me too. Except I ended up with a Lyman Great Plains kit in .54. The GPR is long gone, but I still think about a JB though.

From my end of things, some people on this forum are very connected and knowledgeable. If every anyone from L&R or another big lock company needed my lock or even the whole gun to test fire while proofing their new design replacement lock for the JBMR, I would provide my rifle to them for the effort. Maybe one of them want to just design and sell a spring. Maybe nobody has an ounce of interest. I have not a clue.

You might send a note to R.E. Davis or L&R and ask them. E-mail is in-expensive.

I broke the spring with in 30 minutes after putting it together. My first muzzleloader. If you accidentally drop the hammer without a cap it will snap. Browning sent me a new one n/c. I’m still shooting it 40 years latter.

Warden and I bought ours when the first came out. Shot mine for many years, killed maybe 15-16 deer with it and many targets. It may have been the most accurate M/L "Hawken type" rifle I ever owned. One day, I sighted in on a doe maybe 20 yards away, pulled the hammer back ...mainspring broke.

By that time, all JBMR parts had been purchased by one guy. New mainspring broke first time I cocked the hammer. Ordered two more. Next one did the same thing. Put in the third replacement and sold the gun. That's been almost 20 years ago and the fellow I ordered parts from said he didn't have many left.

Though it's not a copy of any original, it was one of my favorites. The single set trigger was neat and the barrel had deep rifling. Ours were iron mounted, both 50's.

Unless there are mainsprings available, I would not have another.

That is why almost all of my sidehammer percussion guns are Thompson Center, I love the mainspring, and working in the T/C repair depart ent for a year, I never saw a broken one. Plenty of cracked stocks, and other problems, but the locks were very dependable. I know they are no longer made, but there are many, many around for parts.
