lbmarks Posted February 16, 2022 Share Posted February 16, 2022 I am a senior shooter new to IDPA, but experienced in other shooting sports like PPC. Currently I have HP-38, Federal primers, 147 round nose Blue Bullets, 147 grain round nose Bayou bullets that I would like to use. I'm looking for a soft shooting minor load for my Sig P320-X5 that I will use in CO. I've test loads ranging from 3.3 grains down to 2.9 with both bullets. My OAL is 1.114 to 1.115, at 31 feet, holding over a rest. Any help will be appreciated very much. Link to comment Share on other sites More sharing options...
Jim Watson Posted February 16, 2022 Share Posted February 16, 2022 I have shot 3.4 gr HP38 and various 147 gr coated and plated bullets. Hodgdon says that is MAXIMUM with a jacketed bullet. Lyman doesn't even want to talk about it. Your 3.3 may be enough. You need 851+ fps. Link to comment Share on other sites More sharing options...
lbmarks Posted February 16, 2022 Author Share Posted February 16, 2022 Jim, Thanks. The reason I went so low with my powder is there was a guy at the range that had a new chronograph and it showed that my 3.3 load was running 915 fps. This produces a power factor of 134.5. Minor in IDPA is 125, so I started dropping my powder load, and went all of the way down to 2.9. The results are a bullet impact spread of, this is a guess as I don't have the targets here, 1 1/2 to 2 inches. I am a master class shooter in both classes of PPC so I don't think I'm that shaky off of a rest. Link to comment Share on other sites More sharing options...
Jim Watson Posted February 16, 2022 Share Posted February 16, 2022 It sounds like you have the proverbial "fast barrel" and your lighter loads are what Jim Clark called "lobbing." Note that f 125 is the MINIMUM power factor. I like to see 130-132 for a safety margin, I have seen wide swings in velocity from different barrels. I took my P226 to a major match with 9mm ammo developed in my Colt 1991A1. It did not make Minor in the Sig. Fortunately, the rules then allowed for chronographing in the longest barrel of the Division. Mine made Minor in the chronograph operator's gun, so I was good for that match, but I increased the load when I got home, until I retired that Sig and went back to my Colt. It has been a long time since I shot PPC. Back then my Honorary Deputy card got me into matches and on the county team to the state championship level. Since NRA took over from PMA, they are more strict and you have to be a real cop. Link to comment Share on other sites More sharing options...

Blueknight749 Posted January 29, 2023 Share Posted January 29, 2023 I have an X5 as well and I use 147 Gallant bullets on 3.2 grains N320 with an OAL of 1.12 for 130pf. The same load on my Staccato made 124pf. Link to comment Share on other sites More sharing options...
