I know that a modern made 24ga muzzleloader was fired with loads obtained by breaking down modern 20ga cartridges.
I saw the groove cut in the bottom of the flashpan by the gas jet escaping from the touch hole.
The barrel was 1137 gun barrel grade steel. The breechplug was 1015, properly fitted.
I think that this was a particularly stupid stunt. I was pleased that the gun and shooter were unscathed.
In theory, a modern muzzleloader, made with appropriate materials, should be able to withstand the same pressures as a modern breechloader, the loads being within the same parameters.
Unless a manufacturer has engineered the thing to shoot smokeless, doing so would be extremely foolish. There are too many things over which the experimenter has no control.
For example, I mentioned a muzzleloader with a barrel made from 1137 steel. A lot of modern muzzleloading barrels are made with leaded screw machine steel. Machines beautifully, and fast. No way on earth would it be appropriate for a smokeless powder gun barrel apart from .22 RF.
Most smokeless powder rifle barrels use 4140, 4150 steel, 416R, etc. What is the muzzleloading barrel made from? Test firing it proves that it didn't blow up that one time. Doesn't prove that the thing is fit for use with smokeless.
