What size is the flash hole in an Accura using 290 primers? Is it 3/32"?

I am not positive at all about the flash hole size in the breech plug of an Accura, but I'm pretty sure it's alot less than 3/32. The breech plug in my CVA Kodiak, which might very well be the same breech plug as your Accura, has a flash hole that's about the same diameter as a paper clip wire, whatever that is. Just to make sure you understand, the flash hole on an inline is the very small hole at the inside face of a breech plug where the flame from the cap or primer goes through and ignites the charge. Sorry for explaining this if you already know it, but one of your recent postings indicates that you are new to muzzleloaders, so I just want to make sure.

Thanks Mainer for your reply and I am new to muzzleloading.

the flash channel will use a 3mm or 7/64" drill bit to clean it out. The small hole it self is .032"
