Just how big a problem is this? Are a whole bunch of guys blowing up their muzzleloaders all of a sudden? I have been shooting ML since about 1954, and have never seen a blow-up of this type. As long as a shooter uses no more than the maximum recommended load, and seats his balls on the powder, it is not going to happen. But I do not believe it is possible to build any gun so it is idiot-proof!
