Sounds like a good idea!
Years ago when supposedly I was smarter (a few more brain cells to work with back then), and a tad bit more daring, me and a buddy of mine went shooting at an outdoor range in the middle of winter. Temp was below freezing and the wind out of the northwest made it feel like it was -20*!
For some odd reason we were the only two people (i.e. idiots), out there as we had the whole range to ourselves. Only made one trip out to set targets at 100 yards as the snow was like knee deep. Brought along our ARs and surprisingly enough had no problems with them despite the inclement weather. Went through 6 or 7 preloaded 20 rounders before I couldn't feel my finger tips anymore. A sure sign we had been there long enough and we packed it in and headed home.
Still it was a fun day at the range (in an odd but memorable way), and I'm relatively sure that I won't be spending any more time during the winter at an outdoor range!
