OK, guys, can ya help me out, here?
I have two different barrels for my Encore, the factory barrel, and a custom
barrel. In either one of them, I get a horrible crud ring, and 4" groups using
T7 with the 200gr PR DC bullets. Spit patches were used between shots,
but the crud ring was so bad that there were times when it took enough
force to get through it, that the patch had separated threads.
Some have told me that I need to use non-petroleum based oil, or to at
least thoroughly clean out the oil as though cleaning out a very dirty
barrel and using a non-petroleum based oil (like Ballistol) prior to
firing with T7.
What do you guys use for barrel preservative, and how do you prepare
your barrels prior to firing?
