Thanks, appreciate the info!

Unfortunately I am restricted to open sights, loose powder, no sabot or plastic bases on bullets, and the breech must be open to the elements... Good times laugh

I noticed that the CVA breech plug appears to have a small diameter flash hole all the way through, as opposed to the knight breech plug that I'm familiar with has a fairly large hole (1/4" or so) and easy to clean. Is the CVA a pain to clean or can you use something small to easily clean it out?
