Loaded My Remington with T 7 Nov 14th 2010 every evening for the next month I parked in the dryest corner of our screen porch every evening then one morning it was raining so I placed some cling wrap over the muzzle with a rubber band. With Christmas barking at my heels at the end of ML season I didn't get around to fire it till Jan 3d 2011. It was Minus 15F and the thing fired just fine shattering the frozen milk jug of water I had sat in front of the back stop.
this year when I have time I will remove the CCI 209 primer, then the breach plug and push the load out to save the bullet and sabot at least.
The flag on the trigger guard is a great idea, Never know when some thing may happen to you and no body knows that rifle on the porch is loaded.
