I just switched over to using Winchester 231 reloading 230 gr 45 ACP. According to the Speer Reloading Manual #13, the min/max for 45 TMJ 230 gr for 231 is 5.6 to 6.2. Using the Winchester reloading catalog, the min/max for 45 ACP 230 gr FMJ is 4.9 to 5.7. What gives? Is there really much of a difference between TMJ and FMJ? By the way, i am using zero 230 gr FMJ bullets. Thanks in advanced.
