Well, well . . . .

Here is one article on the excess pressure from a 209 primer unseating the sabot prior to powder burn. If there wasn't some truth to it then they wouldn't have come out with the new "low pressure 209 primers". Another article reminded me the reason for using the 209 primer was to ensure the ignition requirements for the new powder "pellets" that came out. My biggest issue was always the 209 breech plug design - this can't help accuracy.
