Michael,
the plot thickens - 2 choices! what does gullo use?
gullo might have discovered this by accident.
I remember the story of him fouling out when blowtubing, and running around trying to borrow a cleaning rod.
the big question was what he would have paid for such a rod.
the general concensus was "what the market would bear".
mpro7 might have been all ha had to wipe with, and it worked.
don,
I am currently experimenting with 5:1 cutting oil solution (Castrol) for the reason we are discussing here.
seems to work well.
this only with pp though.
I am beginning to think we have yet another reason why pp bullets are easier.
just clean the bore well and shoot, summer or winter, same routine.
I used murphy's for a while and it wipes extremely well, pushing easier than any cutting oil solution.
it does however encourage rusting blocks and other parts.
it also leaves a strange coating on the interior of hot barrels.
keep safe,
bruce.
