Try a Nipple Charger?
Or a patch soaked with Isopropyl prior to shooting to dry the flask channel out
I have 3 GPRs.... two in .54 and a .50... all flintlocks. In the .54s, I use 80gr of Swiss fffg and .018 pillow ticking and the .50 likes 60 gr of the same.

I have only a tip for GPR kit builders. Don't even try to use the little wood screws for attaching the escutcheons they break very easily. Instead buy #2 screws from Brownell's or elsewhere and use them instead. The hole in the escutcheon is big enough to accept the larger screws and the countersink are perfectly sized. Drill the correct pilot hole. You can save yourself lots of grief doing these things.
Snap a cap every time, see evidence of clear ignition channel and still have slow fire about a third of the time. Been shooting this particular rifle for 18 years, no such defugalties with any other of my smokers.
I have three of them all kits, darn fine working rifles. I'll be chasing bulls with this one in three weeks.
Have a nipple charger, have never used it. I will….if I can find it….thnx,

I've always favoured the GPR's appearance & construction (Interarms), & I was able to secure two .54 cal. kits after quite a number of years. One was finished with a vintage look, & the other in a polished in-the-white. The latter will be allowed to develop its own unique patina which, understandably, will take some time. Both barrels needed polishing & coning which has been done, & they've become great shooters – easily grouping within 4" @ 50 & 5" @ 100 yds. I've been using a .530 ball, .010 patch over 65 grains of Goex 2F with № 11 RWS 1075+ percussion caps. I've been using the adjustable semi-buckhorn sights rather than the non-adjustible ones, both of which came with the rifles.
One of the included barrel wedges was incorrect. You can see the more rounded shape in the photo. I've since replaced it with the correct one purchased from TOW, of course.
Also, the photo showing displayed furniture includes an unfinished ramrod tube merely for a before-&-after comlarison.
The fit, weight & balance of both GPRs seems ideal for for me. They'll settle right down after mounting that gorgeous, crescent butt plate to the shoulder. 'Course I've asked myself, "Why did you wait so long!?"
The GPR is a stout half-stock while giving subtle flow with its design. My preference remains for the Interarms version over the Pedersoli due mainly to 3 issues (1) the coil spring lock, the longer nose cap & the more reasonable price. It's just my choice & no reflection in any respect is meant toward that of others.

Bought mine in March 2021 from MidSouth Shooters for $687 it was a Lyman Signature Series GPR Kit. It is a .50 and so far I'm using 50 grains of Goex 3f with .490 RB and 0.015 ticking. Just got the Lyman 57 GPR sight and our range has been flooded so I haven't had the chance to sight it in. Used Laurel Mountain Forge American Walnut stain for the wood x2 and finished it with Tru-Oil x4. Did the iron fittings with aluminum black.

Yay! I was going through your first two GPR videos last night -again- (unboxing/zoo bottoms, and Bigfoot). I can’t wait to see this one! I just received my (new to me) 1987 GPR in the mail today, and can’t hardly keep my hands off it.
Keep ‘em coming, Mark!‘Poet

Howdy fellas,
I bought my .50 caliber percussion GPR kit sometime around 1979 or 1980, don't recall for sure, and the earliest target I have from it is dated Sept., 1980. I bought it from a guy who had a table at a gun show at the National Guard Armory in Boulder, CO, the town I'm from originally. I paid $160.00 for it out the door. He told me he had to buy three in order to get a best price from his distributor, kept one for himself and was selling the other two at his cost. (Who knows if that was really true, or not!) The AE stamped on the barrel indicates it was proofed in 1979. Being my first 'kit', it took me a while to assemble and finish it up the way I wanted. I had built other stocks before for some 'unmentionables', so this stock was not my first rodeo.
I did not care for the supplied adjustable rear sight, so opted for an adjustable long classic Buck Horn. I cold blued all the metal, so it wouldn't look too good. I favored the worn look of thinning blue that resembled a patina of sorts. I cut a shadow line accent around the cheek piece and both the front and rear of the stock's side flats. I cut round bottomed accent lines all along both sides of the belly of the stock and all along both sides of the forearm just below the top edges of the barrel channel. I know that none of this is period correct, but to me at least, I could care less about that aspect of things because this is how I wanted 'mine' to look. They seemed to have real nice wood back then.
I can't tell you what it prefers to shoot because over all these years I'll bet it hasn't had much over a hundred PRBs through it. Haven't had the time to shoot any of my guns the way I'd like too, so maybe now in semi-retirement I'll find more time to devote to the sport. Great thread! Thanks for sharing!

WOWZERS'S Clint that is one sharp gun!!!!
Well, Mr. B P Maniac Shooter, I checked out the Lyman GPR Fun Day video, and realized I had seen it before ( but heck, I’ve seen all of your videos more than once). So, of course, I watched it again! Thank you for putting them out there. Next time I get to go “home” to Kentucky to visit my in-laws, I may have to swing by Maysville and check out the zoo bottoms.
I also noticed something missing from my GPR photo from earlier…I think these are better pics

I have three of them. A .50 caliber Flintlock that I traded for, a .50 caliber percussion I bought for a song at a yard sale. It looked like it had never been cleaned. The barrel had been saved by the previous owner using wonder lube in the barrel. My guess is that it kept the oxygen from getting to the barrel metal to cause corrosion. They are both very accurate with both 50 grains 3f and 70 gr 3f and a .490 ball and a .015 patch. I had to finish the inside of both barrels using 0000 steel wool on the cleaning jag, a hundred strokes of so. It made a huge difference in loading and fouling.
I recently bought an Investarms new rifle in .54. The lighter barrel by 10oz make a big difference in match shooting. Left shoulder is about worn out. It has a problem though. The barrel wedges fall out. The factory says not to hammer the wedges or the wedge staples. Has anyone had this problem and if so what would you propose as a solution? Judging by the scratches on the cleaning patches I will be swabbing this barrel with the 0000 steel as well.
