I'm about to start loading for a 9mm again after several years. I sold off the one 9 mold I had. I've a bunch of 38/357 molds including the light and middleweight 360-640s. Other than sizing boolits down 2-3 thousandths, will they work okay in the 9mm?
Considering buying the MP 9mm mold, but already have the 640s on hand.
