Was a bit bored stuck in kodiak hotel for day 3....so here ya go.
Kimber Montana rust after the trip:
Tikka CTR rust after trip really only limited to the first couple inches of muzzle:
And the Barrett fieldcraft that never left the dry tent vestibule:
The Tikka did fair the best despite seeing by far the most direct saltwater on the barrel everyday in the packraft.
Hard to tell from the pictures, but does the Barrett have a rougher blasted finish than the Kimber? Is the Tikka perhaps the smoothest finish?
Alaska, there is this really neat stuff out now...it's called gun oil, really great stuff, you keep your guns clean and boom, they don't rust, whoda thunk it could be true.
