I do not know but will hypothesize that severe pressures were sometimes experienced. Perhaps the solid walls of the case did not cushion pressures and/or maybe the flat internal base of the hull created problems. In drawn hulls the mouth of the primer is well above the hull's base. Internal ballistics absolutely baffle me and weird things happen when any one ingredient is changed.

Thanks Joe for the information. The loads that have been shot out of the Parker were provided by Tom Armbrust and were low pressure.

RST makes great shells for these old guns. I also shoot a 1913 Parker VH and use RST 5's on pheasant and 7.5's on quail and dove. Love the patterns and performance!

It may well have just been a general recommendation based upon ignition of the charge. A lot of the early brass shells were designed for black powder & used a relatively mild primer which was adequate for black but not for some smokeless powders. Parker may well have just thought it advisable to recommend not to use smokeless rather than to sort out which ones gave adequate ignition & which ones didn't. Also if the top wad glue job didn't give an adequate pull about equal to opening the crimp of a paper shell you could end up with a squib load using smokeless. With black as long as it kept the shot from rolling out of the hull you were OK.

2-piper - thanks, it makes sense. In todays market, Mag Tech produces extruded brass hulls and uses large pistol primers. The internal dimensions of Mag Tech hulls are oversized prohibiting the use of modern 1-piece plastic wads. Whereas, 209 primers are standard in RMC hulls, as are gauge specific internal dimensions allowing the use of modern 1-piece plastic wads.
