I use the grease, just the way I was first taught and it works for me.
I will tell you that I was shooing with a guy who was using the wad in his Walker and I was using grease in my 51 Navy. I agree my way was a lot messier, but I'd wipe down my gun between loadings. This guy's .44 Walker got so dirty with fouling and the fouling got pretty hard that he satarted having real problems with cocking and loading the gun. It wasn't caps falling down or anything like that, it was definitly the fouling. I just wonder if anyone else ever experienced something like that. He was shooting pretty stout loads in the gun.
I'm not averse to trying the wads, I might try them in my gun and see how it works.
