I left one of my '58 .44 Remington's loaded and locked away for two years (as of September 9, 2007 when I took it out and shot it). I loaded it on September 5th, 2005. I had put a little note with the revolver with the date loaded and notes about the loads.
Anyway, I never intended to leave it loaded that long, but month after month passed and I never even thought about it until I came back from this years state ML shoot and was putting away a pistol. Anyway, I thought to myself that I should take that revolver out and fire it, which I did the following weekend.
All five loads went off without a problem. I didn't notice anything unusual, the powder seemed sound, the caps seemed as strong as any others I've shot recently.
When I loaded this revolver it was clean and free of any oil. On looking the revolver over before firing it I did not notice any rust or anything at all out of the norm that would indicate anything but a clean revolver. After firing it I cleaned it and inspected the cylinder chambers and they look normal. :thumbsup:
