I'm currently working on a load for a 230 gn lead TC for my 45. Acp.....unfortunately I'm finding a pretty large difference in OAL between my Lyman cast bullet handbook and my Lee 2nd addition. The Lyman states 5.2 gn at 1.170 OAL and the Lee states 5.1 at 1.270...that's 0.100 difference...which is fairly large.....am I just being paraniod or what?
