Lyman Great Plains rifle

[deerstalkert]

i have a .54 GM barrel on mine at the moment. also have a .50 stock barrel. both shoot better than I.
when i consider my collection, the GPR is in a tie with my own builds as the last that will ever be sold.
I shoot it about 50/50 with a TC Hawken topped with a GM barrel. just don't get much better for utility guns. others are much prettier but the GPR will bring home the bacon.

Don`t know what happened with above post, computer froze then posted.

Have a GPR and love it. Couldn`t get it to group first off till I began laying a patch of worn bed sheet on top of my Ticking patch for a tight fit. Now hole in hole type stuff.

There is a couple thicknesses of Ticking; 15 and 18, I think. Somebody said to take a caliper micrometer to the fabric store to check it! I got both types at the gunmaker's fair. Your accuracy is amazing!

I could have worded that better over a bench Ragged hole yes sometimes hole in hole stuff on a 50 yd range. Believe me my shooting accuracy isn`t amazing.

I had issues with my Lyman/Investarms flint .50 Great Plains rifle, mostly eating flints and shredding patches. After some shooting, the bore smoothed out and the patch issue went away. It was reasonable accurate. However, it ate flints too frequently and I ordered my first custom flintlock to replace it.

My lock was the same, plus never could get the pan to seal. Gap on the hinge side.
Got a L&R replacement, the thrill is back, 50 + shots per flint. Was disappointed at fit and finish of lock. Still needs a good cleanup and tuning. But it a shooter.

The Lyman Great Plains was made by investarm. The Great Plains was a rebadged Investarm Gemmer Hawken marked as the Lyman Great Plains. Exact same rifle. Lyman is no longer selling muzzleloaders so no more rifles marked as Great Plains. If you want the same rifle Investarm Gemmer Hawken here is a link to find one. Lyman never ever ever made the Great Plains. They have always been investarm rifles. Lyman was just the distributor.

I have two GPR cap guns in .54. One is date for 91, the other is an investarms but not dated that I can fine. When did Investarms make them?

As stated, InvestArms made the rifles marketed here by Lyman. InvestArms is still making them and using their naming convention.

I just got a newer unfired 54 caliber cap one newer made on I think it was a signature one.

If it`s a Lyman/Investarm it has a 1-60/66 twist rate and the Signature series made by Pedersoli have 1-48 Twist.

Here's a well spoken tribute to the GPR from 11bangbang.

Not that it matters, but I agree with just about everything he says, including the bit about ML hunting season.

Love mine...here is a new one being unboxed if you're interested:

I agree with everything you said. Thank you.

Yes, also recall the Lyman-branded Remington percussion revolvers; they were really nice, I don't recall who made them, Uberti or Pietta, etc.

Right before the stupid covid shut-own, I saw at a tiny semi-rural show, a NIB Lyman Investarms flint GPR. It was $400, but I simply was not in the market for one at the time. What an investment it could have been; it had an exceptional, nicely figured stock. Believe it was .50 cal. I could probably get 600 for it now!

Art, I think you are right but $400 to $600 in that time period means you'd break even w the new hyper inflation fad. Still would have been a smart deal though. You certainly wouldn't have lost anything and who knows what its future would be ? SW

If you’ve gotten this far already you know this is a rifle that folks just like or love. They aren’t perfect but what is? Pick your ignition and caliber and go enjoy. The fact that most owners wouldn’t consider selling them is testimony enough to their reliability and accuracy.

The Gpr was my intro to flint guns. Mine was third hand when I got it. I have it still for many years. Shoots great. I did buy a second barrel for it. Dont remember why. It sits in the closet.

Have yet to put my GPR through a good testing. It was colder than than a mother-in laws smile out with ice on the ground the only time I put a few rounds through it. So I have yet to establish how accurate it actually is. However, as of now, I absolutely love that ML. Its a 1990 year model that has had very few shots through it. It is, overall, in very good condition. Appears to be a very well built, solid ML. I plan on loading it up this week or next week to do some real testing with it now that the weather is nice.

As of now, the only way this one is going away is if its taken from me.

As I've said before here, if these fine rifles were available just as they are, back in the early 1800's before cartridges, they would be the "Hawkens" of their day; very desirable and valued. Best of luck with yours! I do agree with the alterations some guys are making as to stock shape, etc. Whatever sparks your frizzen!

Wouldn’t part with mine for the world. Great shooter, and I got lucky, haven’t found a single thing that I dislike about it.

 

[DirtyDusty]

It would be nice if someone would start importing them again. I have been searching for a .50 GP hunter, but no luck. Only came accriss one online and it was higher than I wanted to pay. The gemmer hawkens is still available, but it has the slow twist bbl and I shoot conicaks for hunting.

Not sure if you need new but you could possibly look for an ugly Betty .50 and have it rebored to .54 w/ a faster twist. If you get a GPR in .54 you wont regret it. (disclaimer: not sure 50 to 54 rebore is possible but I believe I've read it here)
