This question may sound dumb to some but I need to know what the right answer is. I have been reloading .45 cal for my SR1911's using W231 and Bullseye. Next I will be using Power Pistol (6.9 grns) and the COAL that I use on Berry 230gr. RN is right at 1.250. In reading other forums, I have seen people who are using 1.2 as the OAL. Some are using Bullseye and some use W231. Are they saying that 1.200 is the actual bullet length? I TRY to keep mine all at 1.245 min. and 1.255 at max length. With a 1.200 doesn't that drive up the CUP pressure? Why is there such a disparity in bullet length. I know that many use SWC 180 grn. and some at 1.85 grn. but I have a real problem with the length being so short. What is the rule of thumb when it comes to the correct length. I know the type of powder and bullet size make a difference but .45-.55 is quite a difference. My pistols take 1.250 and they seem to feed fine and eject fine. Can someone set me on the right track?
