I'm just beginning to use black powder loads in my .45colt CAS matches.
My first loads worked great.
I loaded up FFFg (with a little compression)
a card punched from an orange juice carton
a 1/8 (plus or minus) lube wad (Felix homemade)
and a 220gn home cast bullet from wheel weights.
I was able to shoot 8 stages with no cleaning from my two Dragoon conversions and my Marlin lever rifle.
I loved the performance but it took way too long to load these up by hand.
I will be trying Dick Dastardly's Big Lube bullets next loaded on a stouter column of powder with no cards or lube wads.
