razmuz: by the sounds of your barrel length you might be shooting a Model 38. I haven'tloaded the 120-125 grain bullets but for the 140 grain Speer the accuracy load from my old Lyman manual lists 42 grains of IMR 4320 for 2577'/sec, more than enough for any Whitetail, Blacktail or Mule Deer you will find. The factory duplicationload for that 140 grain bullet is listed with 42.8 grains of IMR 4350 for 2631'/sec, and both loads were tested with the Husquavarna Model 38. Hope this helps. Mikey.
