Rell it rained 6 of the 9 days and we were also on a raft going through white water often. I took plenty of Remington wipes with me and paid very close attention to it. I also removed the metal from the wood on sunny days to dry it out. It got soaked almost everyday.

93x64mm the load was 70 grains of Varget and a .422 400 grain TSX flat base Barnes X bullet.
