I tried out my MP 359-147 gr mold. I was having trouble getting all the cavities to fill out. With the sprue handle in place, it gives very little room to hold the mold handles. I try to hold them without exerting too much pressure. The nose of the bullet fills out but the bottom is hit or miss. I tried adjusting the lead flow and all that did was for one cavity to spill over into the next. I tried filling front to back and back to front no help. Pot is set at 730 F.
