I've heard of people using bullseye to help ignite big loads, not that I'd reccommend it with today's better powder technology.
I've heard of Elmer Keith experimenting with duplex loads a lot. He sacrificed a lot of handguns in his pursuit of knowledge though too.
I bet alot of nice SAA's are gone over this.
Today, I bet it wouldn't expensive for a guy to rig up a pressure barrel and some pressure inducers before blowing up a handgun or rilfe.
Only if I had more time on my hands.
