Best Flintlock Replacement for Lyman Great Plains Rifle

Ferret Master · Aug 15, 2022

I have ordered a flintlock replacement barrel for my Great Plains rifle. Is there an aftermarket flintlock that will fit so that I can use both it and the factory percussion lock without removing wood? I want to be able to use both locks.
Thanks,
Ferret Master

Without removing any wood the best option is to find GPR flintlock. I don’t know if Lyman is still selling them or if you have to find a used one.

I've got no idea but would a chambers builders lock suit?

Check out L&R locks. Their booklet says they have a lock to fit Lyman rifles.

I put an L&R flintlock in a CVA Frontier stock. It wasn't exactly a drop in but I only spent about an hour doing a little chisel work and sanding.

Yup they sure do. I have one and it works great. But you will need to do some fitting for it.

Sounds good. Where did you find a flint barrel for your GPR? I have a percussion GPR and am wanting a flint rifle. I like what you are doing. They may be the way I would like to go.

Midsouth still had them as of this afternoon.

This is from Track of the Wolf , click on this L&R's RPL-05-F Flint Lock to upgrade Lyman Great Plains, Cabela's, or InvestArm Hawken Rifles, right hand only, made in the USA, by L&R Lock Company - Track of the Wolf It would be way better than a Lyman made one .

Thanks. They still have the 50 caliber barrels but not the 54 caliber. But a 50 would work. The barrel is $352. When I bought my GPR from Natches way back in the early 1990s I paid about $230 for the completed rifle. Oh well.

The L&R lock shows to cost $212 with 2021 prices. So for $564 or so I can go dark. Hmmm? Gotta think about this.

Mattioc (sp?) has a flinter for sale here for another $100.
Might be worth it to save a lot of effort, and to have 2 guns. :dunno:

I can buy the entire rifle from Hinterlands for $680. Yes it is more, but $350 for a barrel only? Not for me.

I was at the range shooting yesterday with @BigAl52; he was shooting his Lyman GPR, with an L&R Replacement Lock…never misfired, great shower of sparks…gun always went off. Admittedly, a lot of this goes to the skill that @BigAl52 has with a flintlock, but yeah…I’m convinced. That lock is amazing.

Aren't there two different renditions of the Great Plains rifle? Most were made by Investarm, but for a time they were made by Pedersoli. You will have to make sure to get the right one, I doubt they are interchangeable.

Yes, original ones were Investarms, later ones were Pedersoli ! I do not know it they interchange or not. I imagine they did not change it very much if at all. It was successful and sold well, so there really was no reason too. IMHO

The new GPR are made by Pedersoli and are Pedrsoli expensive. Now Investarms make a GPR but calls its a "Gemmer" Hawkens plains rifle.

https://muzzle-loaders.com/collecti...er-rifle-plains-rifle-50-cal-flintlock-ia3410
The rifles Investarms used to make for Cabelas and others is now called a "Bridger" Hawken. Also formally referred to as the Lyman Trade Rifle sans patchbox and double set trigger.

https://muzzle-loaders.com/collecti...-bridger-hawken-rifle-45-cal-flintlock-ia2414
Cabelas now carries a "Hawken with the same style patchbox they have always had and its made by Pedersoli.

All I can say is what a tangled web we weave.

I am seriously considering an Investarms Gemmer Flintlock. I have an orig Investarms GPR and love it. I am hoping these are as good? Not sure about the coil spring Lock, but I have not heard any issues on it, heck Ruger went to coil springs on their products? Go figure

T/C has used coil spring locks since they started. I have never heard of one breaking. You are more likely to break the traditional flat springs than a coil spring. No they aren't true to what was made in the beginning but they work and are reliable. I'm not a reenactor trying to relive life 300 years ago so don't really care.

My first muzzle loader was a T C Hawken I built from a kit . It was a nice accurate rifle and got me interested in the historical part of black powder shooting . I discovered the rifle wasn't a copy of an origional Hawken , and the coil spring was not historically correct . I bought a Uberti Hawken and sold the TC . No regrets .
