Hornady 9mm 125gr HAP loading data....

[duece71]

All,
I have done a google search and cannot find any data for this bullet. The current Hornady manual doesn't have it either, it must be a new bullet. I am about to give Hornady a call but thought I would put this out there to see if anyone can point me in the right direction, thanks!

My older Hornady manual shows using the same data as the 124 gr XTPs.

The HAPs are pretty new, but Sierra makes 125gr projectiles in 9mm (.355) and has for some time. I would start with this data and work from there. 125gr is 125gr, soit can be a good starting point. Google points me to this: http://www.reloadersnest.com/query_bw_handgun.asp?CaliberID=6&BulletWeight=125

I think that Hodgdon's books show a Sierra 125gr FMJ, as does Alliant. I have some HAPs on backorder from Sinclair, so whenever they show up, that is what I am planning to use.

I load the Hornady 124 FMJ-FP with 7.0 grns of Blue-Dot. 2nd Gen Glock 17 shows ave velocity of 1240 FPS. Book max is 8.0 but the most I can get in the case is 7.8 grns. Very Compressed load and Vel is 1265 ave.

Hornady is pretty good about supplying load data to those who request it. OTOH you can use essentially any load data meant for an XTP of the same weight (124gr as it seems).

Honestly most of us who were reloading 15 years ago started out with data that only listed a bullet weight and if it was jacketed or lead. We figured out a usable OAL on our own and worked up the load data watching for pressure signs. That approach works just as well now as it did 15 years ago.

I found the answer I was looking for from another forum. The 9mm 125gr HAP bullet is actually listed in the .38 Super data section. So it looks like the bullet was actually intended for .38 Super. I think it can also be loaded in 9mm, just that some different data will have to be used. I am going to use the Hornady 124gr XTP load data and go from there. I will work it up slowly and see what I can come up with.

The 38 super uses 9mm bullets they are 100% interchangeable while the load data is obviously not. It wouldn't be any different than using a bullets in a 38spl that was meant for a 357 magnum. It will go down the bore just the same.

The industry standard cartridge length for 124 grain JHP 9 mm loads is 1.120", such as Speer, Remington, Federal, Winchester, etc.

The Hornady JHP's and especially XTP's along with Montana Gold JHP's, are designed to be loaded much shorter.

I don't know about the HAP bullets, but I wouldn't be surprised if they are similar to other Hornady 9 mm bullets.

Typically, round nose 9 mm bullets are loaded longer and truncated cone (FP) bullets are loaded to JHP cartridge length.

The Hornady 9 mm bullets are non-standard compared to most others though.

^^Hitchhiker,
I experienced the issue with Hornady XTP in 124gr. Kicked my ass for a while as I loaded to the length in the Hornady manual but the cartridges would not chamber in XD or Sig P6. I had to to under 1.058 to get them to chamber....Recommended length was 1.060 (if I remember correctly).

All,
I did a test batch with the 125 gr HAP using Power Pistol. I used the Hornady manual data for 124 gr XTP. I went with 2 loads, 5.3 and 5.7. The max load in the Hornady manual for the 124gr XTP is 5.7 and I decided to go with 5.3 as I am just using these for range use. 5.7 gr of PP was pretty snappy. No signs of over pressure though. COAL was right at 1.060 and they chambered fine in my BHP.
