Re: Rust in bore after a week or so?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: madd0c</div><div class="ubbcode-body">Being in NY I wouldn;t think humidity in an air conditioned house would be an issue, but in the South (where yes I defintely knew what earl was), being in an airconditioned house is by NO MEANS a guarantee of sufficiently low humidity to prevent rust.
The Naval Standards Institute list 50% humidity as the lowest humidity that can form rust, so down here in earl country, I keep a real dehumidifier in my storage area which is indoors and air conditioned. Without the dehumidifier, the humidity can reach 70%!!! I keep it at 45% and use the Kroil mentioned above after I initially had a rust scare. None since then.
Might want to check the humiditiy in your storage area if you have a Kestrel or something to do it with.
Also, I have an "indicator" sitting on a shelf in the storage area. I quickly found out that my LE Wilson case guages will rust in a freaking heartbeat if not kept oiled after using them, so I stuck one of the less used calibers out on the shelf after cleaning it in acetone to remove all the oil. Now every time I go into the area, I can see if any rust has formed on the indicator. Yes, I am paranoid now.

Humidity is something I was going to mention too. The humidity is normally 40-45%. But I just figured I would mention the low temperature, because if I'm not mistaken the lower the temp the less moisture the air can hold. Good to now that 50% is the lowest that can cause rust though. In the winter the humidity gets even lower because I heat the house with a wood stove.

Condensation resulting from suddently changing ambient temperatures from outdoors to indoors, vice-versa may induce rust in a bore or elsewhere metal is unprotected.
Solution: Apply liberally grease to the projectile of the last round of the range session. Drop the greased round onto the ground in an area rain has gently washed silt onto. Roll the round around with the sole of the shoe. Right or left will suffice. Abundantly coat the bullet with fine dust and or dirt. Pick it up. Dust off the case, but not the bullet. Chamber the round. Fire it. The fine grit scrubbed out any primer, powder, carbon, and copper residue remaining from the range session. The grease lubricated the bore preventing rusting in the interim before the next enjoyable range session. For a finer lubrication and abrasive, fire a non-dirty bullet, but not more than one, as your final round. This round will impregnate the metal pores with mineral spirits from the grease for a longer lasting rust preventative.

Condensation is another thing I was going to mention lol. That Is the reason why I try to not move the guns as much as possible from there air conditioned room(yes the A/C is on 24/7 just for my guns) to another. Thanks for the great ideas too.
