Looking for Load Data for the 'Matts Bullets" 165 Grain DEWC, .452, ( I do not know the old Ideal or Lyman Mold Number ) for use in a usual 5-1/2 inch Barrel S & W m1917.

Seems like this Bullet could be fairly snappy while remaining within safe pressure limits.
Anyone have any experience with this one?
