I keep a 3/16" wooden dowell in my gun case. If another round gets jammed in the chamber you can use something like that to push it out from the front. Be careful not to use any metal tools to pry a stuck round out by the rim. If you crush the rim, the round could go off .
I use Miltec 1. If half of the claims on the web site are valid ( http://www.militec1.com/ ), then it is awesome stuff. But if you ask 10 people on this forun what lube to use, you will get 10 different answers.
