Larger Flash Hole

[bummy]

Hello everyone.
My question is, will opening up my flash hole from .0625 to .070 dia. on my flint lock rifle make ignition more reliable?
Thanks.

Yes, and less accurate.

Why do you ask? What kind of ignition problems are you having? There might be another and better solution if you're more specific about why you ask.

Never heard that before. Respectively, why would such a insignificant larger TH make the gun less accurate? I would agree that velocity and foot pounds of energy will lower using an equal volume of BP. Not saying you are wrong just don't see the relevance.

Get a numbered drill set. You can go up to a .0630 or .0670 first. I have had good luck with the .0630. Just a little larger but it helps. Also make sure the breech isn’t caked with fouling.

I bought a Invest Arms Hawken style rifle .50 CAL. new from Dixie Gun Works. I had reliability problems with ignition. I've tried every thing that I know, my club members know, our forum knows and YouTube knows.

new English flints, tried both bevel and bevel down
.062 flash hole dia. in the sunset position
4f powder in the flash pan (Goex)
50 gr. 3f main charge (Goex)
.490 RB
.018 thick pre lubed patch
flash pan powder towards the outside and inside of flash pan
tapped on barrel to make sure powder is in the patent breech
picked flash before each shot
Sometimes I get flash in the pan but no main charge
Sometimes it goes off okay
Sometimes hang fire
Tough to shoot when it's like this

Bought a new L&R lock, didn't work any better

I'm so frustrated that I'm thinking of buying a Kibler Woods Runner with hopes of better reliability.
PLEASE HELP!!

Well, that will definitely solve your ignition problem, no doubts here whatsover, though rather a drastic and expensive and time-consuming solution to the immediate problem.

Fix this rifle first .... THEN .... get yourself a Kibler!!

Any ideas of what to try next?
