I sent the following question to Western Powders on Buckhorn 209 and received the following reply from Don:
Galen,
It's always good to hear from someone associated with the Modern Muzzleloader forum. I believe this is the most knowledgeable group of shooters out there.
Although BH209 is a new product, it has been in development for many years. During the development stages it was tested in very cold conditions, down to -40 degrees Fahrenheit. All indications are that BH209 will perform very well in cold conditions. Quite frankly, you can't get me to go hunting at 40 below. Non the less, the testing was done.
The most common reason for a hang fire or delay fire is a fouled breech plug. I am certain you are aware that you need to clean the fire channel, this is the area from the primer pocket to the flash hole, with an appropriate size drill bit. This area needs to stay as close to new as possible. A perfectly cylindrical fire channel promotes good gas flow, this is a must for reliable ignition. Check with Busta, I believe he has had several posts on this very subject.
As you have noticed, the brand of primer can also effect ignition. There are three very important characteristics that primers provide for ignition. Pressure, heat and hot particulates. Our tests have shown that the CCI 209M primers provide the most pressure and particulates. These primers will foul the fire channel faster than Federal 209A or Winchester W209. The Federal had the second highest pressure of the primers tested and less fouling than the CCI 209M but more fouling than the W209.
note - This testing was done in laboratory conditions, your results may vary. Also remember that primers can change from lot to lot as well.
Another point worth mentioning is breech plug design. Ideally, we like to see the primer sealed. A system that provides a good primer seal has NO blow back. This assures that all the primer energy is directed into the powder where it is supposed to go. A good test is to fire a primer, just the primer. If you have a good seal you will not see any black on the walls of the primer. The primer should look almost as clean as it was before you fired it. Refer to the attached picture. These are both Federal 209A primers. The one on the left is a less than ideal system, the one on the right is a very reliable system. The point is that a very good primer with more than adequate strength has actually been reduced in energy by the design of the breech plug. Not to mention that I hate cleaning that gun because of all the blow back that is obviously not necessary!
Back to your original question, the testing has been done and BH209 does perform well in the cold. The important thing to remember is to keep your breech plug clean. Always start your range session or hunt with a clean breech plug.
We appreciate the honesty and integrity of the people using the Modern Muzzleloader forum. Please keep us posted on these issues. Our goal is to provide the best product and service in the industry.
Best regards,

Subject: Blackhorn 209
Can you tell me if Blackhorn 209 has been tested extensively at temperatures in the teens and twentys (F degrees)? I'm currently on my 5th can and have not had any ignition problems, but all shooting has been done above freezing. A few guys (Modern Muzzleloader Forum) have recently had hangfires or failure to ignite at all in temperatures below freezing! Most of us are using Federal 209A primers (hottest) and one member even had a hangfire with this primer; although most were with Win. and CCI 209 primers. If you have any information that can help, I will share it on the Forum. Obviously, a good tight sabot fit with substantial pressure is understood. No one wants to believe its the powder, as we are ALL very impressed with it and will use nothing else!
Thanks,
Galen
