I hear you on temps. Unfortunately, I live in AZ. For half of the year, temps are over 100. From a shooting perspective, I envy your location. The next four months should be good for us down here in Phx.
When we get as cold as tonight willl be I'd rather be where you are. It'll hit -20 here tonight if it goes anywhere. It was -6 when I shut the truck down this afternoon and rather windy. I won't even try to drive my car tomorrow; my Volt hates it below zero so I'll leave it plugged in and drive my Durango. Dodge trucks will usually start to -40 without using a block heater. I've seen -45 with my last dodge.
As far as fireforming using loaded ammo; shooting a slower cadence, ie. a round every few minutes while you are working with something else will help a lot. Using just enough pressure for a good fill will also help; you don't need b#11s to the wall stuff for fireforming.
