It's the X-treme 230 RN that I use, which is .452

When I run a large batch of 230g 45 ACP through the Dillon, they're going to be plated X-treme, Berry's or HSM. The X-treme & Berry's are .452. HSM FP 230g are .451 The more expensive jacketed Hornady & Sierra's usually end up on the single stage press.
