Misfires and Hangfires

[davy]

BTW does anyone have the dimensional measurements (length and diameter) of the powder chamber on a GM 50 cal barrel breechplug and the same for the TC 50 cal breechplug? I am wanting to turn down a fouling scraper for each that will fit well into the plug to remove the gunk.
Thanx :thumbsup:

Davy, I have a few TC scrapers that I never use...the reason is the TC P/B is a continueous taper from the top of the breech plug down and around to the vent (or nipple)...with the taper constanty getting smaller and smaller the whole way...so those little curved tip scrapers only just barely get into the top 1/4" of the P/B. (I have a couple used, spare TC plugs I keep around for "show & tell")

What works far better is to simply thread a CF rifle brush (.22/.25/.30 cal size) onto a cleaning rod, and use the brush to grip/hold a damp patch and slide it all the way down into the P/B...rotate it around a couple turns and voila, a clean P/B...follow it up with a dry patch, then even a lubed patch if you want to.

Soaking / cleaning the hooked breech barrels in a bucket of hot soapy water has kept the P/B's spotless for me, avoids any buildup.

Sounds good! That was what I was also considering doing as I have a bore brush the rite size, but need to get an adaptor for the proper thread size.

Thanx RB

Davy

If you had been in a CW conflict you would be dead. Find someone in your area who is a CW buff and they can help you. There are lots of guys here who know their stuff, but first hand info is always the best.

I still feel the pluging of the nipple is either a problem with the caps you bought, the nipple has a undersize hole in it (less than .027), or both. :hmm:

I'll have to dig out my feeler gauges to measure that but I have several nipples, Red Hots and Hot Shots and all the holes look the same. Actually I have the original std TC nipple and it's hole is larger than the high performance ones. I should mic the paperclip I use as a nipple cleanout as it's very close to the size.

The caps are number one thing to try next weekend at the range. This kind of problem takes all the fun out of it.

Exactly what I thought. That's why I posted my lengthly epic here.

As for someone in my area, with it being winter most of the muzzleloader guys at the range are in-liners.

Bighole,

Have you checked to see if your barrel is one of the ones with the helicoil?

Bighole,

Yes. I had mentioned I just got mine for Christmas but the serial number was prior to the ones listed on GM's site. There's no helicoil in my barrel.

I'm sure the solution is simple for those that have been doing this for a long time.

So what's YOUR solution other than asking someone else at the range? I'd sure love to have more input. I got til this weekend to compile my solutions to try.

I'd rather be shooting than fixing while at the range especially in the cold weather.

Well, if it is so simple, what is the cause of the problem?

Bad powder---- bad caps----- could be bad lube also and could be bad nipple as well. Good luck Bighole. Where are you located? :thumbsup:

I cured my hangfires with 3F powder. Reduced loads of course.
