Great rifle...fabulous workmanship! I love the lock, and THEIR PANELS. Most mountain rifles I see have fat panels, and though they may be HC I prefer the narrow ones like yours.
Melt some chapstick into the "taller" hole. It makes very nice patch lube, but you need to saturate that patch - not just wipe it on. I use Lube 103 and apparently, it'[s just chapstick.
