8-)I watched this thread carefully and have concluded conclusively: you all live where it's too *&%# COLD.

It was so cold yesterday that I needed to jump start my chemical hand warmer. My Prochrono has an extra compartment in the battery box that I have been placing a hand warmer in. They come in packs of two and I had left one single in the truck over night -17. The thing was stiff and would not fire up. I put it on the defroster to warm up the hand warmer. And it is a banana belt here compared to what RAF enjoys.
I have been anxiously awaiting some global warming.

It is very cold everywhere north of RB's place. -6 this morning here in WNY. -38 way up in Maine. Great for Ice fishing.
If it ever got that cold during deer season around here, I can guarentee my gun would fire....cause it would be leaned up against the gun cabinet inside.

I would not expect a very large decrease in velocity with the 300g bullet/44g 4759 load. Various criteria were set for book loads: 1) not over 50gs of powder, 2) always goes off, 3) 1 1/2" or less @ 100 yds, 4) low temp variation of velocity. 5744,4759, and VV-110 all meet this criteria very well.
The big test to me would be the H-4198, VV-120, various duplex loads, etc. The 2015 loads, single powder especially, in the 40 would be interesting.
There will be significant drop in most loads, and this is to be expected and accepted if the drop is not too much. This is where a fast twist really comes in as the groups tend to stay tight even with a 200+ '/sec velocity loss. Ask a benchrest shooter what his very slow twist groups would be if 200'/sec were lost. Slow twist is very accurate at fast and extremely consistent velocities - benchrest shooting where you can chase your "ideal" load as the temps go up and down a degree or 2: but for a hunting gun, a very fast twist provides excellent accuracy(close to the benchrest type of accuracy) over a very wide velocity range. When I get another barrel(likely PacNor) for my Kevin Rayhill 223 Sav sporter, it will be 8 twist even though I normally shoot only 40g NBTs(hog/deer hunt with 53 Barnes/60 Nosler Partitions - never lost an animal or had one go even 100yds!!!). Fast twist and hunting go hand in hand, IMO.

I have another data point to add to the thread.
I am using 43 grns. of N110 with a 50 cal. sabotless Thor bullet and a Fed 209A primer. Like wilmsmeyer said it was -6 last night and below 5 degrees when I fired my load out of the gun this morning(Not quite as cold as where tar12 is but dang cold). I left the gun outside all night and fired it out in the morning. Mind you that load has been in my gun since the second week of Dec. last year during NY muzzleloader season, never got a anything to shoot at that week.
I was doing two tests the first was to see if I could keep a load in the gun and not have a moisture problem, and I was extremely careful not to expose it to temperature extremes and second would it fire in extremely frigid temps. It appears I have success on both fronts and the load went bang and hit a 8 inch wide dead tree at 50 yards a couple three inches above where I was aiming which is spot on for my gun.
I got a Christmas chrony and look forward to using it, but like tar12 said I was not about to fool with it in these temps. The good news is I will be doing a lot of testing with the Thor bullet and N110/N120 using a Fed 209A primer starting this spring and look forward to sharing my results much like all of you have done to help get me this far.

my gun went bang this morning after being out all night at -6 in wny. had it loaded w/ n110 and a 250 xtp sb mmp that went down real tight. no delay , just bang. i'm cofident this will go off next hunting season without going pfffft.

I shoot the N120 only and would be very interested in a couple things
1. did it misfire in more than one gun.
2. As the temps increased when did it stop misfiring or as the
temps dropped when did it start.
3. When loading was the load (hard, moderate, or easy) when
loading.
at this point the velocity means nothing if the gun will not go BANG!
Deadeye and I have been running or own long range testing the last two weeks avg temps have been low to mid 20's and with over 40 shots a piece for a total of about eighty, not one misfire....now -14 is a little extreme for me to be hunting in however I am interested in finding out if there is a temp threshold for N120....and if -5 is the limit then that will give me an excuse not to go out and look like a big sis to my huntin buds..."sorry guys I can't hunt with you my gun won't shoot in -10 weather maybe next time".....Thanks for the info and look forward to More info on this....

Elkboy,
it did misfire in two different guns, I dont know how but it could have picked up moisture, I dont remember which gun but it misfired at the range last summer too.

We just finished the Illinois Late Winter Season this past weeken d.It is a does only affair. We had bitterly cold weather. Minus 8 Friday morning with winds. 15 above and windy was the high for the day. I was not interested in testing my personal tolerance for cold ,so we watched the field from the trailer. Apparenly the deer felt the same way. The MLII's were left out in the back of the truck. I will add that it was harder than chinese math to load the MLII'sThursday evening.. We went out in the afternoon Friday and had no luck.MLII's go into the back of the truck. Saturday morning dawned cold ,12 degrees , light winds and the first doe fell at 7:30am. BO ,N120,fed 209a did it's job. It warmed up sunny to the 40's Saturday afternoon and 6 more does were harvested, 3 of which were taken with MLII's ,bo,n120,fed 209a from noon to 5:00pm.
We did nothing special with these loads. IMO, the ignition problems always come when the you have rainey,drizzely ,sleet,snowey conditions when the temps hover around 32 degrees. In short moisture. When it gets as cold as it was this past weekend, the air is incapable of holding any apreciable amount of moisture and the temp would have to rise above freezing for the moisture to become a problem.
Just my opinion.
