Touch Hole Liner Problem

[Mongo40]

Went out this morning an sighted in my .36 rifle, got it on target at 25 shooting 40grs of 3F, it shoots a lot better than me, but I cheated an used a sled to get it just right. Here's my problem, Had a lot of flash in the pans with it not firing the rifle, I noticed the hole in the vent is a lot smaller than the one on my .45, as my vent pick wouldn't even fit in it, here's a pic of the liner

I cant tell by a photo how big the hole is but I use Chambers white lightning liners and I put a 1/16 th hole in them an never have any problems so you might try that :thumbsup:

What kind of powder are you using? That can make a HUGE difference.

 

[Mongo40]

Goex 3F

The powder probably isn't the problem then.

Drill vent hole out to 1/16" and cone it slightly on the outside & also cone the inside of the vent liner. Also make sure the vent liner is not protruding past the bore. If it is you need to shorten it to the barrel wall length. I have use allot... of them Ampco bronze alloy vent liners & once coned a tad, seldom have a problem with them. The ones on the left are Ampco vent liners. These are coned for a large bore rifle so you may not need to cone the outside as much. Just do a little & try it. The inside come is the most important, as it lets the powder get up to the vent hole easier.

Load the rifle, take a gem clip & straighten out one part of it, run it thru the vent hole into the powder charge, wiggle it around & remove it. Load 1/2 pan of 3F powder in the pan & fire it off.

Be aware that your gun will foul up differently in different weather conditions. I you were shooting in hot, humid weather conditions, you will probably experience a lot of wet, gummy fouling, requiring more cleaning between shots. The fouling will build up on the frizzen, the flint, the pan and the touch hole area, causing misfires or in the touch hole causing the flash in the pan

Be careful drilling out that vent with a screw driver slot in it. The slot may catch on the drill & snap it off. I'd suggest putting a small bevel on the hole with a larger drill before drilling it out.

Fortunately or unfortunate for me where I live there is no such thing as humidity, its always hot and dry, especially this time of year, (SW Okla.)so its perfect conditions for shooting a flinter.

I checked an a 1/16 bit wouldn't fit so drilled it out, just need to cone it a little an also the frizzen doesn't open all the way every shot so I'm thinking the spring may be a little strong on it, what is a good way to fix this, file the spur on the frizzen down some so it opens easier?? Thanks for the help guys, once I get the bugs worked out its going to be a sweet little rifle.

Are you sure the frizzen isn't opening all the way? Could be rebounding. After the shot if the hammer is fully at rest and the frizzen resting on it then that's probably the case.

Fairly common and not a big deal unless it is smashing you flints when it snaps back.

Enjoy, J.D.

Well.... obviously one would drill it from the back smooth side, thus not catch the slot. Some things ya just do & not thing to say why. :idunno:

If the lock is lighting the pan every time, leave it alone. Just lubricate the frizzin pivot screw with oil, & take a toothpick & put a smiggen of lithium grease where the toe of the frizzen rides on the spring & try it. It may be just tight & will work itself out.
As mentioned, it could be frizzen rebound, but regardless, if it is lighting the pan every time & working & not damaging the flint, best leave it alone.
I have seen many a good lock messed up by monkeyitus.... :wink:

If it is a Chambers built lock, you could send it to Jim & he will fix it for Free under their Lifetime Warranty... and have it right back to ya in a few days.
