HAP 125 grain data/cycling issues

[fxvr5]

Here's some of my old titegroup data from a 5" Kart barrel;

125 HAP @ 1.095 OAL titegroup 2.8 gr = 846 fps

125 HAP @ 1.095 OAL titegroup 3.2 gr = 950 fps

125 Zero JHP-RN @ 1.100 OAL titegroup 3.2 gr = 938 fps

125 Zero JHP-RN @ 1.100 OAL titegroup 3.6 gr = 1054 fps

125 HAP @ 1.095 OAL titegroup 4.0 gr = 1152 fps

The 4.0 load just barely equals the speed of factory ammo.

With all standard caveats - this is data from my gun and all guns are different etc.

Yeah, If you had read my original post, you would have seen that I did load and shoot ten rounds to test function before going any further. You would have also discovered that those rounds were in fact at Hodgdon’s max for a 125 grain HAP in 9mm. Ten rounds wasn’t enough, true, but your implication that I just picked a powder charge and “loaded up a bunch” isn’t accurate.

I do, in fact, know what a charge ladder is. Having loaded and shot literally tens of thousands of 9mm projectiles over Titegroup, I don’t always do a fresh ladder for every new projectile. This comment, combined with your continued mention of reducing my oal when I already told you how short they are shows me that you either haven’t read or understood the information I provided.

Thank you for attempting to help me. Please feel free to share your experience with this particular projectile. I would welcome it. I would love to benefit from your other advice as well - once you demonstrate that you have actually read and understood this situation. Thanks again for your input!

You did say you shot 10 rounds but you did not indicate you shot other loads. My bad if I missed that. We have a lot of new handloads on this forum and I see it quite ofter just picking a number and loading. It was not meant to be offensive, just information for the novice.

10 round is normally plenty to test function. Normally I see Hornady running the wimpy loads, not Hodgdon's. Like you something is amiss with that one. My only though is that they may have got a very hot load of TG. Like you, no 2 guns are the same. Just a though what temp are you testing these at. Here in TX it can be 80 one day and 30 the next. I'm in area that is not suppose to get above freezing for 60+ hrs coming this weekend into next week.

Hopefully the load you have now will work out for you.

FYI: All 50 rounds with 3.8 grains of Titegroup @ 1.07 COAL cycled my P320 flawlessly and grouped well. Problem solved. Thanks to those that offered their pertinent experience and advice.

Yeah, 4.2 is a target load tuned for accuracy (shootability).

And I am just some guy, don't use my results for load data.

Lol. 3.8 grains @ 1.07 cycled my P320 fine and grouped well. I’m sure my normal 4.0 grain load with 124’s would be fine. Thanks again for your help!

No worries! I’m in Texas shooting indoors. 3.8 grains cycles fine. I’m convinced that the 124 grain xtp data is safe with 125 grain HAP bullets.

I wanted to revisit this thread to thank fxvr5 for taking the time to type out and share the excellent data. Thank you sir!

You're welcome. Glad you found a load that runs in your guns.
