It does after about 1500 rounds you set the barrel back a turn. In some respects the Plummer remindes me of the old 30-30. .30 cal and 30 grains of powder, well the best load for the Plummer with a 50 grain bullet is 50 grains of 4064 and a 50grain bullet. the 50-50-.224 Sounds like one of the old black powder cartridges, sort of.
