I have reloaded .45 ACP for many years. Always used Bullseye and once in a while Unique if I was out of Bullseye. Have always been able to find 9MM ammo pretty cheap and don't shoot much of it. Now 9MM has gotten scarce and expensive. So I bought some dies and 125 grain cast bullets for the 9MM. Was going to use Bullseye ,but talked to a guy who said Win. 231 was much better for 9MM. Cleaner, more consistent and better accuracy in a wide range of guns. Have Bullseye and Unique on hand. I try to keep as few kinds of powder around as I can. Will shoot the 9MM in a variety of guns so I am not really looking for the very best load for one particular gun. Just want something close to factory velocities that will function and be reasonably accurate in any gun I use. Should I try Win. 231 or stick with Bullseye? Thanks, Waldo
