First time I heard about the teflon tape, that sounds like a good idea. Will it will workfor my T/C Omega breech plug?

Troutman, what kind of propellant did you use? Pellets, BP, T7, Pyro, BH209? Some foul more than others. I am only 4 months old to MLng myself and am still learning. I thought this was going to be a new hobby that I could just mosey on through but........no. I am all in. Welcome to MLng and all these folks here are great sources of information. I learn more and more every day.
