Re: forward ignition?
I believe R. Gibbs was one of the pioneers of forward ignition. I don't know much about his work but I think his cartridges ranged from .244 Gibbs to the .505 Gibbs.
Midway lists a cd-rom for reloading for the Gibbs but I have no knowledge of its' content. Not much help but good luck with your quest.

Re: forward ignition?
Creighton Audette did work with flash tubes in magnums but he is long gone and I don't think he ever wrote up anything on it.
As I remember he did them on the steel head cases but I haven't seen anything about steel head cases in a long time.

Re: forward ignition?
Are you refering to the methods used to ignite large bore (cannon sized) shells such as the 155mm's?

Forward ignition via flashtubes go back to the 40s or before. It was tried by Elmer Keith and some of his friends. They also tried duplex and triplex charges along with the tubes and others such as Rocky Gibbs tried both but no one continued it.

I actually have a recipe from an old, and now deceased 357 shooter who had some triplex powder loads. I didn't feel like having 3 charges to meter out per load and I just use H110 for hot 357's but those loads that this guy had come up with were HOOOOT and they still came out of the pistol looking fine.
He was old enough that he'd be about 95 now if he was still alive, he had quite the list of stories including some about Mr. Keith as well. I wouldn't be surprised to find out a lot of them were true.
My dad knew him from our Church, I was about 10 when he died.

Re: forward ignition?
McMillan was experimenting with a round the called the "fat mac" back in the 1990's
It was a shortened 20mm case necked down to 50 cal. Basically looked like a 6mm br on steroids. This has a flash tube that was cross drilled to light off more of the short dense powder column at once.

Re: forward ignition?
I think the OP is talking about Front Tube Ignition. From my understanding, there were some experiments with this 30-40 years ago. There were a number of theoretical benefits but the experimental benefits were somewhat inconclusive. From what I recall there were greater advantages in larger cases (cannon) but with small arms, the difficulty fabricating the front tube ignition in the cases out weighed the internal ballistic advantages.
Basically a small tube was screwed or soldered to the flashole; during ignition the powder would burn from the base of the projectile down to the bottom of the case (opposite of what currently occurs). This way the heat of combustion remains in the case and there is less throat erosion. There seemed always the danger of the ignition tube becoming detached and logging in the bore.
