OH........MY..........GOODNESS!
Wipe er' down if she's wet...just what you can see, not the whole firearm!
I don't think I know, or really want to , anybody that would yank an action out of a stock on a daily basis if hunting in inclement weather!
Talk about having to check zero before the hunt! I bet that's going to torque off the rest of the crew, you blasting several rounds to check your zero at 5AM in the mourning because you just dropped your action back in the stock! lol hehehehe
Look...before hunting season, you prep your equipment for combat, do you not?
Action out of stock, put a heavy coat of your favorite protectant on the entire rifle!
I like to use Butches Paste Wax under the stock line, or on the entire rifle for that matter... it will last forever under the stock, where it's not rubbed on. (here come all the 'I use this' posts...but good, we need ideas, right?)
Once the 'hidden' parts of your rifle are coated with some kind of protection...all's that is needed, is to wipe off the dew drops on the exposed parts.
And IF you have applied a good protectant(wax) you don't even need to wipe it down, shake off the most of it and go eat!
What do you think is happening to your rifle after you have mopped all that rain off of it, I mean you just came into a 75 degree hunting camp from the 14 degree outside....that's right, condensation! everywhere on/in that rifle!
Remove the action after hunting season and do your prep for next year!
So, like many things in life, protection and preparedness is the answer!
