I just got off the phone with Accurate Powders. I went over a couple loads I have worked up. First is my 4.1 gr @ 1.130 OAL with 124gr FMJ. He at first said it was over pressure. Then I questioned the new data we all have which list 3.5 GR as MAX but also List 1025 FPS out of a 4 inch barrel. He said he had been quoting me lead data so he redid things. I could hear him typing in the background. Then he said it was a safe load based on my OAL and my FPS using a chrono. So I went on to the 3.6 gr 147gr @ 1.130 OAL load Ron59 has been wondering about so much. He said that I (Ron) was not getting nearly the FPS he should be. BUT, that he was loading very long. All their data is at 1.100-1.114". He ran the numbers again and said "based on the FPS, that is a safe load". I asked him what he meant, because it sounds like he is using FPS as a guide to pressure. He said if you work it up on a chrono and don't try to exceed the FPS they have listed in their guide that FPS is a better indication of pressure in your gun. I am summarizing all this but still find it very interesting. Old and New Data can be found here. http://www.brianenos.com/forums/index.php?showtopic=78983 Wanna kill these ads? We can help!
