Hadn't heard of a baffle used in it. I have had a Square Deal B for 45acp for years and no problem with it so never looked for any solutions to anything Dillon wise but I just recently got into using the 550C for 223 so besides about 400 rounds through it I have had no experience with the ins and outs of possible issues till now. There is a bridge looking bar in the bottom of the powder measure if that is what you are talking about.

Not sure if that is the exact issue, but something to think about. Pretty easy to make your own since it's just a bent piece of metal.
