DaveInHawaii Posted January 2, 2017 Share Posted January 2, 2017 Hi, I want to load up some of the HAP 125 in 9mm. Published load data is hard to find. Hodgdon data is very conservative and seem to be concerned about pressure. http://www.hodgdonreloading.com/data/pistol They list Titegroup starting load at 2.8 and a max load of 3.2 (33,700 PSI) with a COL of 1.069. It's the same for HP38 but they give a max load of 3.3 with HP38. For you guys that load the HAP 125's have you seen anything weird happen with the pressure? Personally, I'd like to try these with Silhouette powder and I'm interested in using the load data they list for the 124 XTP which is: Starting load 4.6 to 5.4 max with a COL of 1.060. I would load it longer if it chambers. I'm wondering what your thoughts are? Thanks, Dave Link to comment Share on other sites More sharing options...
jcc7x7 Posted January 2, 2017 Share Posted January 2, 2017 (edited) The older Hornady reloading guides list the XTP and HAP together and show the same loads for both. are you loading these minor or major power factory ? or just loading for practice/ self/home defense etc?

DaveInHawaii Posted January 2, 2017 Author Share Posted January 2, 2017 Thank you for your reply. I'm loading for practice and don't need to meet any kind of power factor. I'm just looking for accuracy. Thanks, Dave Link to comment Share on other sites More sharing options...
jcc7x7 Posted January 2, 2017 Share Posted January 2, 2017 BASICALLY you can use any 124/125 gr jacketed load in the mid range of the loading charts and get good accuracy and functioning. Generally speaking the starting charge weight is what will reliably function most guns slides Link to comment Share on other sites More sharing options...
Philip Dedmon Posted January 2, 2017 Share Posted January 2, 2017 I have loaded some of the 125 HAP's with Shooters World Clean Shot, 4.2 grs. with a 1.135 OAL. Those are in the 1050 to 1100 FPS range out of two of my G34's and a Single Stack 1911. If you don't have any Clean Shot try some Tite-Group or N320 at the same 4.2 grs. and go chrono them.

DaveInHawaii Posted January 2, 2017 Author Share Posted January 2, 2017 Great, thanks for the info guys. I appreciate it. I was impressed with the consistency, accuracy, and cool temp of the Silhouette powder I tried with some Zero 125 (.356). Thanks, Dave Link to comment Share on other sites More sharing options...
al503 Posted January 2, 2017 Share Posted January 2, 2017 Pressure is going to spike with such a short OAL. Regardless of the powder you settle on using, you might consider loading longer than what the manuals list. I try to load as long as the mags/barrel chamber/case neck tension will allow, to keep the initial pressure spike as low as possible. Unless you're loading for a very short freebore like some CZ's, you should be able to load a lot longer than 1.069". Link to comment Share on other sites More sharing options...
DaveInHawaii Posted January 2, 2017 Author Share Posted January 2, 2017 Hi, I'm with you on loading as long as possible. In this case it is for a CZ and I can go out to 1.090 on the Zero 125s. I have not checked the HAP 125 though. Thanks, DF Link to comment Share on other sites More sharing options...
DaveInHawaii Posted January 2, 2017 Author Share Posted January 2, 2017 Sweet, good idea. Much easier than going back and forth adjusting the Dillon to get different COL. I'll try that tonight. Thanks, DF Link to comment Share on other sites More sharing options...
Philip Dedmon Posted January 2, 2017 Share Posted January 2, 2017 Did not know you where loading for a CZ. My HAP's @ 1.135 are for a couple G34's a G17 and a G19. Link to comment Share on other sites More sharing options...
DaveInHawaii Posted January 3, 2017 Author Share Posted January 3, 2017 Cool, it's all good fellows. Here's the back story...a while back I called Hodgdon to ask why their powder charges were so low for the HAP bullets. The tech support guy said that they found a difference in the thickness in the jacket between the two bullets and thus the pressure issues with HAP. That seemed odd because I thought they were the same design. So, I called Hornady and the guy I spoke to said he thought the jackets were the same but he didn't want to go into any details on load recommendations. Who knows? Hodgdon definitely feels there's an issue and I figured you guys probably deal with the HAP bullets more than anybody else. I wanted to keep my initial posts simple to not complicate things. I'll load some up, start low and bring my chronograph. Thanks for the help. Dave Link to comment Share on other sites More sharing options...
