Howdy,
I'm new here. Just signed in. I've marketed and sold hundreds of Big Lube(tm) molds for SASS main match shooting. They are intended for fast action timed fire main match stage shooting.
Here finally is a black powder bullet design bullet that can be shot hundreds, maybe thousands, of times without need to clean to maintain accuracy or function.
The original, now well proven, designs are now widely recognized as state of the art for fast continuous no hassle shooting. This Big Lube(tm) technology is now finding it's way into long range shooting. Several experimental designs are showing great promise.
The holy grail of shooting dirty and shooting accurate may have at last been found. As learning happens I will try to post results.
