Most any anodized aluminum ramrod is going to get marred up quickly. Just degrease it and repaint it once in awhile.
My Accura rods have never been extended and work just fine for field loading. Everyone should have at least one good range rod... even your wives and girlfriends.
I can't recall ever reloading more than twice in a day while deer hunting - with any muzzleloader I've ever owned (and generally a second load was only because I wasted one for whatever reason).
Yes, Breechplug, my Accura barrel cleans up very easily. Mine also shoots cold right in there with the fouled ones, as does my Apex.
That's 2 different 3-shot groups fired over a month apart - notice the red #1 (cold/clean).
