You guys must be having the same system we are. Our place reached 31 below, my folk's place was 35 below, and a neighbor a couple miles down the road said 42 below.
Needless to say, we've dug out the long johns.
Nice! Should shoot really well! I know my two anniversaries do! BTW, after shooting them a few times they make dandy hand warmers before the next round of shooting .
I have trouble shooting mine with the yellow disc in, so I take it out...
