Last week I told you of a guy at my local range who blew up his .45 cal. He said he used Power Pistol and loaded it to 9.5 grns. I am setting up my Dillon Square D for .45 using Power Pistol and looking at charts, I am getting confused. Gunslinger, Magnum, and VT (Bob) gave me the sights to look up and there is a discrepancy. Alliant states for .45 cal. 230grn RN plated, COAL is 1.2 and they call for 9.5 grns of powder. Disclaimer on front states to download 10% which makes it 8.3grns. I went to the sites the guys suggested and then dug out my old Lyman's book and it states: Power Pistol is 6.4 starting to 7.2 max. charge and COAL is 1.270. VT(Bob) said that in his Hornady book it said for a 185 SWC max. charge is 9.5. which may have been what the guy at the range used. I never gave it much thought until he told me his story and now, after looking at all the loading manuals, I am concerned. I am tempted to start loading Power Pistol @6.9-7.1 grns or should I start say @6.7grns? Alliant bought up a bunch of powder producers yet fail to put out any good loading data. I want the same recoil as what the manufactured rounds are so that way I am used to the recoil and don't want to loose my ability to fire a round and be able to focus on target re acquisition. What are your thoughts and suggestions? Would appreciate any feedback. BTW my COAL is about 1.255-1.257.
