I just ran into this, http://www.thebuckskinner.com/omega.html 25 ACP Brass primer kit for TC muzzleloaders. Ever get that one shot out of the blue that goes off target by about 3" to 4" we call them "flyers"?? It could be the 209 primers that your using.
Some believe these flyers were the result of the 209 actually lifting the projectile off the powder charge simultaneous with igniting the powder. The much milder Small Rifle primer of the 25 ACP case ignites the powder just as instantly but lacks the energy to move the projectile off the powder charge therefore eliminating the flyers.
