What powders are easy to ignite in extremely cold hunting situations? Are duplex loads intended for better cold weather ignition or should single powder loads be used?

You will get many opinions here.
Here is mine for a .50:
From EXPERIENCE....A good dose of H4198, (76-80 gr with a sbaoted 250 or 68-72 gr with a saboted 300) tight fitting load and a FAD209A and never a misfire.
Keys to success? DRY barrel. Load and shoot. No Rem oil, no lubes. No patching between shots ever.
Been doing this for many years with a .50. Cold for me is single digits in mid December. Lot's of dead deer in ML season.

Reloder 7 works for me in a 45. Down to negative double digits in nebraska

I look at it this way: Which is easier to ignite, pistol powders or rifle powders? Therefore, I duplex year around using pistol powders as a primer powder, just to be "almost" certain.
On the other hand, most get along with a single such as H4198. Probably boils down to personal preference as what to use.
Wilms gives excellent advice for barrel conditions.

Some powders ignite better than others but that doesn't mean they will not be temp sensitive even if they ignite in the cold. Same with duplex, some combo's just don't work well when the mercury dips below freezing.
Stick with that 10/50 load you are shooting, holds up well in the temps you will see come hunting season.

Back in 2000+/- 1 year, when the temps dropped to below zero here in NE AR and SE MO(where Toby was), Toby Bridges asked that I try to record the velocities of 5744, VV-110, Ltl Gn,4759,4227,3400 with 250 and 300g XTPs and compare to what we'd been getting thru the summer and fall. 5744 pretty well kept its slow speeds, 3400 did nearly as well, but VV-110(at 45 and 46g with 250g and 1 g less with 300 g) kept nearly it's already hi velocity. You didn't mention what caliber. So, VV-110 held its velocity with massive temp drops, VV-110/VV-120 /250g bullets went from 2700 to 1900 at 70 degrees and 0 degrees. Big drop! However, 58-62g VV-120 seems to have relatively small drop. No one seems to be able to explain this.

sw... I kinda lost you on the amount of loss witn N110 . Frist you stated N110 "kept nearly its already high veloity" but later state " N110-120/250gr. bullets went from 2700 to 1900 at 70 degrees and 0 degrees" I would be interested in the loss with the other powders . Thanks , mrbuck

I shot 4759 in what I call cold weather. It was about -5 deg F and killed yote. Was about 85 yards and hit exactly where I was aming but I never able to shoot for groups or over a chrono with that temp. Load is 43gr and a BO.

sw... I kinda lost you on the amount of loss witn N110 . Frist you stated N110 "kept nearly its already high veloity" but later state " N110-120/250gr. bullets went from 2700 to 1900 at 70 degrees and 0 degrees" I would be interested in the loss with the other powders . Thanks , mrbuck I had little to no loss. Some others(think they were shooting 43-44g VV-110) had up to 100'/sec total loss. However, the duplex of 110/120 had massive loss (2700'/sec with 70 total g, 250g bullet) with a load that really wasn't that low pressure. IMO, with a 50 cal, it is very hard to beat, 45g VV-110/250-300g bullet, WW under sabot. 2500 '/sec or 2400'/sec 250/300g.

sw... Thanks for helping me understand your experiments . This past Saturday morning it was in the 60's in the morning and I shot my Savage MLII SS( a stock gun , no extra tune up ) . The load was 44.0gr. of N110 , a 250gr. Parker Balistic Extreme in a MMP short sabot . and a CCI209M primer . Three shots clocked 2389f.p.s. at 10 feet and put those three shots in 1.210" . Fifteen minutes was allowed for cooling between loading . Does WW stand for Wonder Wad ? Many years ago , I used the MMP Sub under their short sabot . Thanks again , mrbuck

SW. Thank you for the time and testing it will save a lot of us from having to do the same. Good info.

Anyone who hunted during the Iowa late Muzzleloader 2013 season felt the cold. A solid week of straight below zero temps and a few nights of minus 10-20 with a gun loaded with H-4198 and a saboted 195 Barnes had no problems going off and finding it's mark on the last night of the season. Good luck and thanks to all!

I went back and looked at my shooting logs: 45.5g VV-110, MMP short, Wonder Wad, Win 209, 250g XTP varied between 2430-2450'/sec. I think there was some different barrel dimensions with the early barrels or possibly the fact that many of us lightly lapped our barrels allowed us to shoot higher amts of powder. The owner's manual actually stated, " VV-110, 44g +/- 2gs with 250 or 300g bullets. So a book load could be 300g bullet/46g VV-110.
