A very good read.
The 17* part shouldn't be cold enough to cause adverse body control issues. Much colder than that with some wind will begin to make a big difference.
I especially appreciate the author's recommendation to get out in the foul weather and do some practice.
Where and when I hunt weather can change from nice and sunny, to rain, to heavy wet snow and to dry and windy snow. You'll learn alot from foul weather practice as far as personal comfortably , shivering etc, is concerned.
Also you'll lean alot about protection of your equipment. Darrel mentioned fogging of LRF, typical occurrence. When the weather is right or wrong, if you will, generally means loss of optical equipment, scope, spotter, LRf when they fog from breath. This goes for glasses also, to which I can attest.
Then there's the issue of moisture in the action/trigger. I recall being set up for yotes with a rain/snow situation and temps just below freezing. I was prone on my little knob. 4 yotes came from nowhere. All of a sudded they were just there. The farthest was @ 495 the closest was about 200.
I was shooting a 270 Win on a mauser action w/timney trigger. I lined up on a the yote at 350. Broke the trigger.....nothin...... no click no nothin. Opened and closed the bolt. Did the trigger thing again. Again no results..........
I think I went into panic mode...... Repeatidly opening and closing the bolt and by now just pulling on the trigger. Next operation was to breath on the rear of the bolt to attempt to increase temp and unfreeze the trigger. Had to repeat this several times.
By then no yotes were in view. ****........ All of a sudden I spy one at about 70 yards! Oh well, here goes again. Mean while my buddy, doing the rabbit squak all along, to which none of the yotes were giving any attention, was wondering what all the movement was on my side of the sage brush.
I line up on the 70 yarder and I'll be dog gone if ol' Betsy didn't go bang.
I that situation would have been a trophy buck or any kind of elk I'd be still feeling miserable with the memory.
I have since developed a combination scope/action cover that so far has preclued that situation.
Darrell points out some very important points.....
