eldequello,
Have you been to the prbullet web site and read what they have to say about the 209 primer being to hot? They claim the 209 is so hot it lifts the sabot off the powder charge causing fliers.
Toby Bridgeshas an article on the variflame primer adapters on hpmuzzleloading.com After reading his article and others like it, I feel it's worth a try.
I'm still skeptical, but I'm alsocurious and I want to eliminate those unexplained fliers.I'm looking forward to giving this a real workout. I just need some good weatherand a little time.
