I've had 2 1851 Pietta 44s sitting in my garage for the last 2.5 years since I shot them last, both pistols loaded and ready to fire, one is a Sheriff model and the other is the same but I slapped a 1860 snubby barrel on it. Point is, I'm in Phoenix, and in the summer I bet it gets up to 130 easily in my garage, these things have been loaded, all 6 cyclinders in both, 30gr of powder and Remmy caps on both seperate cyclinders. They even had blue coppering around the bottom rim of the caps they've been loaded for so long. Last Friday morning I went to go sight some red dots in at Phx Rod and Gun so I threw both the 1851 .44s in my range bag. After sighting in my Trijicon, I took pistols out and every single cylinder went bang in both of them, no misfires, so second strikes, all worked first try and smoked the place out. I was absolutely impressed, even bought a new nipple wrench the week before because I figured I was going to be taking these things apart to get the powder and balls out. Nope all shot perfect after at least 2.5 years loaded surviving the AZ heat!
