Awoken some .54 Cal Maxi-Balls from a 30 year slumber. The lube is done and it almost looked like lead oxide build up. Thompson Center no longer makes them, other options are available. Undecided on lube at this point, Bens Red or Beeswax/Olive Oil for lube grooves. I have some Bore Butter, but read it gets runny in the heat. Will be applied via pan. Will be rolling with this round for Deer/Elk this year. I washed my hands A LOT during this, careful not to touch my phone, rub eyes or point at my brain. Lengthy soak in mineral spirits. Life anew, ready for some lube. Only 6 more boxes to do.
