Well I have heard excellent reports on Blackhorn 209 propellant for muzzleloaders. I tested it out yesterday in my CVA Magbolt .50 rifle. I shot two loads and the first one had a couple mis-fires where the powder did not ignite. I removed the breech plug cleaned the flash hole, reinserted the breech plug and compressed the load again with the ramrod. The load fired but only after a hang-fire. Loaded a second charge and had the same issue. I am shooting Winchester W209 primers.
The two shots,even with the hang-fires were awsome, right on top of each other and minimal smoke and recoil. Has anyone else tried Blackhorn 209 in a older CVA Magbolt.
I found several articles online discussing issues with the flash hole size of the magbolt being .028 and it needs to me more around .035 to properly ignite the propellant. They also addressed the issue with the slotted breech plug causing too much back blow and recommend trying the CVA Kodiak/Apex hex nut breech plug.
Has anyone else had this problem and been able to fix it? I really love the limited results from the limited rounds fired. The Blackhorn also has virtually no smoke and very limited fouling.
