I seat the Lee 228 to an OAL of 1.210" for my 45's. I've read through this thread and
some people are getting too deep into the proverbial weeds over something that's not as big an issue as it seems. Load to an OAL that fits and use the standard rules of load development. For comparison, the Hornady 230XTP is seated (Horn 9th) to 1.210" also, and it's length is nearly identical to the Lee 228, or within a few thousands. By the way, the minimum book spec for the 45 auto is 1.190".
