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.
