I experimented with various of these types. But none were ever put on the market by Super Vel. Might have discussed it with Cirillo on numerous occasions. I do not remember him telling me he tried it tho.Results were not effective enough to warrant marketing. Besides the liability from a primer on both ends of the cartridge would not be worth the effort.
IIRC we put 1 grain of Bulleye in a 405 gr. 45-70 projectile with the primer and fired at a 2x4 was somewhat impressive.
Just lab experiments.
