I just bought a Lyman GPR Flint kit...am waiting for it to arrive, I happened to read somewhere about replacing the vent liner as the one it comes with is not good? Anyone able to offer clarification

shoot it first. if there are no problems why change it. also check your warranty restrictions before you mess with it. i have been shooting stock size liners for years without issues. many are fixing things that aren't problems imo.
Mr. Stubert is correct.
Also replacing the touch hole liner will not void your warranty. Geeze!
The as-it-comes from Lyman liner will work but it leaves a lot to be desired. I rate it as the worst thing about a Lyman GPR. It WILL fail you and it WILL fail you at the most worstest time. :hmm:
I can't imagine anybody saying anything good about one. :shocked2:
And.............

He did not say he was having ignition problems. He only said he "read somewhere" it was no good.
He needs to shoot the thing before deciding if any changes need to be made.
Take yer time and decide later what you want.

Certainly the touch hole liner from Ox Yoke is a good one but let me offer this one for your consideration http://www.flintlocks.com/parts.htm
You will need to scroll down to Chambers "White Lightnin'" liner. I have put them in several of my flintlocks over the years and they are great. With either one, you will see a marked improvement in your ignition. I don't know about the Ox Yoke liner, since I have never used one, but the hole in a Chambers White Lightnin' liner is too small for the average hunter or target shooter. You will need to drill it out to 1/16 to get the best ignition. Chambers makes them small for better shot to shot performance by bench rest shooters. The occasional misfire or "klatch" is worth the improved shot to shot performance. But, a hunter is not looking for that level of shot to shot accuracy and will benefit from a larger hole that will give a positive ignition on each shot.....if the shooter does his part when priming the pan. This need for a 1/16 inch hole for positive ignition will be true of any replacement liner.
Consider both liners and pick either one and you will experinece a marked improvement in ignition. I just happen to be partial to the White Lightnin liner. Whichever one you choose, be sure that the hole is 1/16 inch.

I replaced the liner on my GPR with one from RMC too :thumbsup:

Does the Lyman even have a warranty? I think the RMC liner would improve ignition and it's an easy upgrade.

The White Lightning used to require re-tapping and if they still do, they would not be right for a gun that is still under waranty. However, I was told that the White Lightning liner now comes in different threads. I can't say one way or the other. I bought several of them a few years ago and have not had to purchase any more since then so I am not sure of the threading issues as they stand today. For those cases where they can be used, they are great.
The link to Chambers seemed to be to the current place and the only liners listed were the White Lightning's with the 32 thread pitch.
If this is true, the White Lightning liners cannot be used in the Lyman guns unless the largest thread size is used along with redrilling and retapping the liner hole to a 5/16-32 thread.

Shoot it. If it needs to be bigger then make it bigger. Sometimes instead of drilling I use a dinky little rat tail file to work it out until it's ju-u-u-ust right.

I agree to some extent. If it shoots OK, leave it alone! If not, first, open the touch hole to 1/16th or 5/64's and then open the back side to 5/32's. You'll want this counterbore to be within .010 depth of the outer surface of the liner/hole. That should fix almost everything. If you intend to hunt with this gun, you'll be glad you have a removeable liner after you get caught out in the rain or snow a few times and end up with a pan full of mud. Not to mention the occasional "dry ball" LOL

I'm pretty sure someone out there makes a direct replacement that is drilled a bit different and improved over the" stock' unit,I just ran a slightly larger drill through the hole,I eyeballed it to be about a 1/16" drill and ran it almost through leaving just a bit of the original hole in the bottom ,this leaves a larger cavity to allow the flash easier entry much as a cone would,if it needs coneing later ,I'm not sure what the proper tool would be but a hardened nail withe head cut off and chucked in the drill would probably work and I can still open her up the rest of the way if I feel the need.The inside hole is sufficiently large that it does'nt leave much to open( on mine).
Don't worry to much about the warranty ,almost any firearm I ever bought had the warranty voided within 20 minutes of me getting it home!It's a thing with me that's why I am not a collector of fine arms,I have to play with them.
Don't blow the barrel up,they won't cover that unless you used the right load110 gr. black powder and below. If a spring breaks send in only the offending unit eg. The lock,or the trigger group or call them and tell them what broke most times they'll just send another ,parts don't cost horrible money.I ask will they replace it,if they don't I'll send the money.Most reputable gunmakers won't quibble about small parts in my experience,especially if they are still in production.

You can save yourself a lot of frustration if you drill the stock liner with a #50 drill. It is very easy to do. Go to the hardware store and buy the drill. Also take the liner with you and find a metric nut that fits it's thread size. Put the liner and nut together. Now you have something to hold on to while you drill it out. You won't damage the threads and all will be well with the world. :grin:
I imagine most of the advice some have given you is from folks that don't have or may never have shot a GPR. :shocked2:

I agree with ebiggs first response. Getting and RMC liner is the easiest upgrade you will ever do. It will significantly improve reliability and speed of ignition.There is no reason to make the modifications required for the White Lightning liner (these are best suited while installing an undrilled custom barrel. You can drill out your existing liner, but the RMC is not only bigger size hole but is also coned out. Besides, for 5 bucks and change, why bother driving to get material needed and taking the time?
