I can't find anything to go in the firehole to clean out the primer residue.
Everything is too big. I have been reduced to using a small allen wrench and a sewing needle to push thru to make sure the hole is open.

This feels not very satisfactory. I have bought breech plug cleaners from Midwayusa that were all too big for the firehole.

Ultimately, I am afraid of a buildup that clogs things up. I have been using BH209 and BH209 cleaner but just can't find anything small
enough to scrub the hole.

Any ideas appreciated.

thanks
