The musket cap nipple on my T/C Hawken has a very small flash hole and I have had some ignition problems.

I am thinking of drilling it out to 0.077 inch. Its the smallest drill bit I have.

Dixie sells aftermarket musket cap nipples with a "small" hole for better ignition and less gas escapage, so they claim. Their hole size is .028.

This is a T/C nipple but I think that must be about the size of the hole.

Do you think drilling the hole out would hurt anything and perhaps improve ignition?

I'm not an expert, but some drilling-out might help. Seems like you're talking an awful lot, though. Maybe somebody else more knowledgeable will chime in here and help you out.

I don't understand why you'd be having ignition problems with musket caps on a T/C. You sure that flash-hole size is the problem?

hmmm .028 vs .077=.o49 i'd try reamin it out first with a nipple pick ,the hawken is a side lock are u usin black or ? pellets may be alot harder to ignite ( of any of the various subs )the trick the old timers taught me years ago was to prime the nipple before i capped it ( well that and shake the powder to the drum side before i put wad or ball down the bore -theoretically helps insure better flash transfer )the priming the nipple trick was also applied if/when the charge didnt go off ,in worse case scenario i've pulled the nips off and filled the touch hole as well
i wont say drill the hole out and would try it only as a last resort ( esp. .050's worth )u mite find a diamond tipped dremel bit that will smooth and polish the top half inside tho tho but again pick ur nipple when done and make sure the drum is free and clear ,powder gases vent where they can ,worse case ? i wont go there ,best case ? new nipples can be had and old friends are hard to replace ( unless it's ur womans nipples ur tryin to replace mine about had a fit way back when i got a old colt that needed new ones and she heard me and my buddy talkin about screwin 6 new nipples in -nope she didnt have a clue what we was talkin about nor catch the whole convo but she heard enough to make her mind race lolz ermm:confused:"

Not at all sure. I was using a couple 50 grain Pyrodex pellets in it with No. 11 caps with good success when I started having failures to fire. I would pour some loose Pyrodex in the the space under the nipple to make it fire. This worked for a time, then it didn't so I switched to a musket nipple. This worked for a while but the last time I used I couldn't get to fire at all. Even filling the touch hole with loose Pyrodex didn't help.

I think that filling the nipple/touch-hole with powder will just create a fuse effect, delaying or impeding ignition. At least that's what happens with flinters.

Were I thee I would pull out the nipple and give a thorough, 200% cleaning to the whole shebang and then try again. Maybe you should consider switching back to the Real Thing and letting the Pyrodex go find a job somewhere else?

have u taken off the drum and cleaned the breech end as well ? if there's a build up in the drum it could actually direct the spark away from charge to the dead side of the drum ,my fav nipple pick is the wire from inside the garbage bag tie ( it isnt as stiff as a true pick but it does get in there and is a lil thicker than the bread bag ties )is it a tc flame thrower nipple or just a regular musket nipple ? ( shouldnt matter as both are supposed to be hotter than a # 11) years ago i used to get some italian caps man them dudes were hot -hotter than the old rws's i think i use the mag 11's now and some cci 10's on the imports but i'm also savin for the 209 conversion on my thunderhawk ( already did it to my american knight)i wont say that pellets wont work but they were more designed for inlines and cartridges,another trick the old timers taught me was a primer charge of a finer grained powder first ( never much but it helps fill the drum ) mite also work with ur pellets say a grain to 5 of whatever brand pellets ur usin ( except white hots no clue there )but the loose stuff say 3f triple 7 or 3 f pyrodex ?the fact that it used to work and now doesnt is what gets me especially since u upgraded to musket caps best i can tell ya is make sure ur drum and touch hole are clear and unimpeded and it ought to work again

edit for DK
actually priming the nipple is a first line defense when a round doesnt fire..well after tryin cap # 2 that is ,works kinda like kindlin' ( sorta ) and is alot easier than having to manually unload the barrel especially in the field ,the modern inlines kinda do away with making it so hard but is still a pita ,only a few granules fit in the nipple and i dont think i ever noticed any more delay or blowback and the only time that i seen it didnt work is when gary forgot the powder( and didnt have a puller) no name(dave) actually managed to get enough powder in the drum that the round barely made it out of the barrel lolz

I have picked the drum heavily with no results. My brother helped me out by removing the screw head to the hole going into the barrel so I can't take that out. But I am realatively certain that the hole is open.

The hole in the No. 11 nipple is almost an exact fit for the drill bit I have. So I think I am just going to drill it out and not use pellets anymore.

Never used pyrocrap pellets in my TC, never have ignition problems with BP. Even loose pyrocrap works. If ignition was ok before, it sounds like a progressive fouling issue. How are you cleaning?

72, If you can't get the screw out of the drum these things are tough to clean but there is a way! I used to clean my 54 Mowrey Ethen Allen by purchasing about 3 feet of Aquarium hose that fit tightly over the nipple. I then filled a gallon milk jug with near boiling water and a Tbsp. of dish soap. I put a tight cloth patch on the cleaning jag and wet it in the solution. I forced it down to the bottom of the barrel and started to use short pumping strokes. Eventually the water would start to flow though the nipple. I'd pull the rod up a bit and continue pumping. Eventually the whole barrel would be full. I'd pump water back and forth through the nipple completely emptying and filling the barrel several times. Changing water as needed. After cleaning I'd run patches back and forth through the barrel until completely dry, blow though the hose to dry the nipple and the oil the barrel completely including placing drops in the nipple. Prior to firing I'd run a dry patch in to remove the oil, fire a coulpe of caps to drive the oil out of the nipple, Load about 20 grains under a wad of paper and discharge it prior to loading for hunting. I never had a misfire in the 10 or more years that I used it regularly. RD

Your cleaning procedure seems very much like mine. I take the barrel out in put the breech end without the nipple in a large stainless steel bowl full of hot water. Pump water like you with a tight patch.

I started shooting black powder stuff in 1968 so I am not new to this.

I forgot that you have that lovely hooked breach. You've got about 5 years on me. I think I started in 73 or 74. Had an Italian made 44 kentucky with that damnable horseshoe shaped butt plate. Talk about a shoulder killer when you have farm boy arms and shoulders. Graduated to the Mowrey. Now I've wimped out and have an Austin Halleck inline. Definitely not traditional but what a rifle.

Didn't start until about '77 or so. I hunted with a TC Hawken for several years, still in the safe. I've since pretty much upgraded to flinters.

Rockydog I knew Bill Mowrey when he lived in Olney, Texas. He had a shop down there and his primary business was making reproduction cannons.

He later moved to Wichita Falls, 12 miles from where I live. He was a good guy.

Charley changing to a flinter is not an upgrade.

When percussion caps are a distant memory and ammunition can only be seen in museums, I'll still be puttin' venison on the table! ;-)

unlike  a few modern ( erm so called modern) the tc doesnt have a round screw in  drum on the side ( those would unscrew btw )  tc puts it all in the breechplug and while i havent found a breechplug online yet i did run across this tidbit

By God, sir, such slander! I suppose next you will tell me, sir, that it is NOT the 10th day of April in the Year of Our Lord Eighteen hundred and nine.

 

Love my flinters! Don't shoot them often enough, though.
