Extreme care must be adhered to if ML powder, ( might be only BP) is placed in plastic tubes other than those designed for such. One of the cardinal rules when ML fad came about in the 70's was not to put loads in plastic tubes. Static electrical sparks could ignite the powder,and several guys had the tubes go off in thier pockets.
Quit being cheap,by the Quickload devices sold for that purpose.
