I never did get great results with the KCRB, or the Kid's modified Remington type bullet. However, I think it needs more shooting, and it seemed to like the lube discs underneath it. I think it will also make a good bullet for a combustible cartridge, with the lube discs underneath it, and the bullet hot-dipped in a lube that it likes. And, shooting it over 26 grains of 3fg, and smashing it down to the max to get it in the cylinder, wasn't "fair" to the bullet. It will require a little more shooting.
