So just a heads up, all of the Internet rumors of frog lube gumming up and causing problems in cold weather hold true. scenario: bolt action rifle (ruger american), 20 degree weather, some snow, snow on the ground, consistent winds. Sat in the elements from 12:30pm until decided to do bore check at 4:30 pm. upon deciding to do a bore check, lots of snow and debris from walking through grown up fields, potential long shot at game looming, I attempt to operate the bolt and clear the chamber, bolt is super tight. Normal pressure not even budging the bolt handle. Start to get the “w t f”’s and point rifle in safe direction to crank on the bolt handle. Couple palm smacks and it’s up. Attempt to pull bolt to the rear, stiff. Palm smacks engaged. Bolt breaks free and ejects from the gun completely, now laying on the snow covered ground. Frog lube in the bolt take down lever had frozen it in the open position. found some weed seeds in the bore, cleared it out and installed bolt per normal after cupping the action and the bolt in my hand to thaw out a little. my bottle will go in the trash and now every rifle I decide to take in the cold woods will require a full break down and clean with something other than this gimmick just a FYI from personal experience.
