I have an Armsport 50 caliber Hawken Flintlock with a stuck touch hole liner. It is so stuck that even an "easy out" won't budge it. Does anyone know what the threads are for the touch hole liner so that I can run a tap through the hole?
Ok, why take it out? I haven't taken a touch hole liner out since I owned a TC hawken 30 yrs ago. No reason to.
Now that you have tried and the hole is probably opened up beyond useable size. the are about a dozen standard threaded liners. The Armsport is probably but not necessarily metric. I'd probably tap it for a SAE size anyway. Since you are in Berks county, I'd suggest you take it up to Dixon's. he'd have the know how to remove it in a few minutes and would have the replacement on hand.
I guess I tried to remove the liner from my son's rifle because that was how I was taught to clean my own T/C Hawken. Having a larger hole makes it easier to pump hot water into and out of the barrel. I tried Dixon's yesterday but apparently they are closed on Wednesdays.
Actually, a proper touch hole liner has no provision to be removed except when replaced. You want the interior powder chamber to permit the powder to be as close to the pan as possible. Even a screw driver slot keeps the powder back a fraction from the pan.
We did keep close attention to the touch hole though. We cleaned the barrel and the adjacent touch hole with moose milk, made up of water, oil and soap. Sometimes put the barrel in a soapy bucket of water. And cleaned it good. A light spray, afterward, of that new WD 40 made sure the hole was perfectly cleaned and rust free.
Like I said, I never heard of changing a touch hole liner. If I get my old body rehab done soon, as expected, the muzzleloader, which dates to before the American bicentennial in 76, is all ready to hunt. Includes the original, unmoved, touch liner.
Some touch hole liners are made to be removed, with a screw driver, allen wrench etc. Some are installed semi permanently and are only changed when firing erodes the hole open too far.
The general sense of most target shooters, is that we want to liner coned on the inside, so there are a few grains of powder visible inside the touch hole. In addition, the closer those powder grains are to the pan, the faster the gun goes off. Now we aren't talking a few minutes or seconds faster, we are talking a few thousandths of a second faster mpossibly even a couple of hundredths of a second faster. For all practical purposes, imperceptable to the average human ear. However, given the movement of the barrel, the game, the natural delay from trigger to ball exit, that very short interval of time makes a difference down range, where it counts. Perhaps not a huge difference, If two shooters of equal ability were shooting two like guns, with the only difference being in the touch hole liners, it might make a couple points different on a 100 yd target in a ten shot string. For the average hunter, not so big a difference. To a target shooter, for whom every point matters, it is a very big deal. Matches, trophies and prizes are won or lost over a point or two.
Now, when it comes down to the consistency from shot to shot, we measure, load, prime, squeeze the triger and follow through as consistently as we can. The touch hole liner is just one more slight thing that plays into that consistency. If you want to keep on pulling that liner to clean your hunting gun, have at it. It probably won't matter for your shooting anyway. Once you get away from production guns and worry about flint, powder toward or away from the liner, breathing, how the light hits the sights, cross breezes, etc, then the touch hole liner will matter more than ever. You will want the powder as close to the pan as possible and those allen screw liners keep the powder too far away.
