RE: Breech plug lube
I am a firm believer in using CVA Slick Breech Plug and Nipple Grease. I used that T/C stuff when I first got the Black Diamond and ended up with two cases of stuck breech plug. One was so stuck I snapped the T/C breech plug wrench that came with the rifle trying to get it out.....
Since switching to the CVA stuff I have never had a problem. I use it on my breech plugs, nipples, and bolster clean out screw threads and have never had any problem backing them out.
I have tried about everything except Slick 50 one grease, but I do have a tube of it. When the CVA runs out I will give it a try.... The Auto parts stuff worked, but was too messy for my tastes.
