Hi to all!

I have been very disappointed with mis fires in cold weather, so much I've opted to archery hunt instead. I'm hoping, from all the great resources here that I can get some more knowledge and advice.

I had a wonderful time using Black Mag powder after i could not get it anymore i switched to black horn 209. the first pound worked but corroded my barrel because I was used to being able to leave a load in after season. new barrel same good results. I met a couple gentle men at a store telling me the horror story of misfires in cold weather using bh209. we compared flash hole sizes, and I gave them the last of my bottle to try. New bottle of bh209 for me and now I have the cold weather misfire problem. tried 2 bottles, same problem. tried different primers flash hole .028, using a knight disc extreme 50.

Advice?

Thanks, in advance.

I had some misfires this winter that I thought were cold weather related. Also in a Knight. Im pretty sure that I narrowed it down to 1 or 2 things. 1) Wrong or old 209 primers- may have been ML primers instead of true shotgun primers.
2) I may not have cleaned my breech plug often enuff or clean enuff.
I am using the bare 209 system from Lehigh Defense instead of the plastic jackets. Leaks zero and has a better breech plug. cost very little to switch. Also seems to light BH209 easier.
 
What primer are you using? Federals are about the hottest, personally I use Winchesters. Be sure the flame path is clear and not blocked or diminished by carbon build up, 209 are notorious for carbon build up. You may need to hand twist a bit to clear the flash channel. Not sure about knight breech plug how long is flame path from primer to powder, you need to deliver a hot and powerful ignition into a tight sealed breech. With cold weather you may not have a tight enuf sabot fit. Plus BH209 is intended for heavier bullets, 300 grain and up for best ignition results. What is loading pressure/effort? You also need a tight non leaking fit for the 209. Just a few things that come to mind. I'm sure I'll think of other stuff that can booger up cold weather ignition. Keep us updated on what you have and can find out about the why of your problems. W

PS go over to the "inline" forum and read through the Blackhorn 209 do/don't and insights and that will certainly help. Your breech plug may not be BH209 friendly.

If you have a red plastic jacket DISC Go here https://www.lehighdefense.com/collections/muzzleloader-breeches/muzzleloader-breeches

Get 2 adapters in case you lose one...NOT NEEDED IF YOU HAVE A BARE PRIMER BOLT ALREADY.
1 Breach plug
1 4 pack of vent liners.

Buy regular Win209 primers and a hex shank 5/32 drill bit to keep the flash channel clean.

I have never had this plug fail to ignite BH209 with a standard Win209 primer. Keep the flash channel clean with the drill bit and change vent liners when they get to around .036. Keeping the flash channel clean is critical. Its not optional and must be done as part of the cleaning routine.
 
wow, thanks everyone!
I'm not positive of the primer type, I'm traveling and won't be able to check for a few weeks. I did buy Federals and a few others but haven't tried them. think I bought magnum primers. Bullet weight, again not positive but I'd bet it's just under 300 as a 45 caliber.
I'm buying your suggested accessories ASAP!
cleaning the flash channel much better is definately something I'll do also.
I'm heading over to the posts you suggested also, really thought I read every thing related but. I'm wrong.
