Powder recommendation for 124gr HP 9mm

[MADDOG]

I'm have a hard time finding data to load Precision Delta 124gr HP 9mm bullets. My reloading books list a lot of others but not much on the 124gr HP. I have Bullseye, W231, Unique and Red Dot. I need some advise and/or where to look for this information. Thanks

I use the PD 124 gr FMJ over 4.3 gr of TiteGroup. I get 1100 fps with good accuracy.

Hodgdon's website has a lot of data for their powders. http://data.hodgdon.com/cartridge_load.asp You can use the 125gr FMJ data, but be careful with the OAL. Since the FMJ and HP have different profiles, using the FMJ OAL could result in less case volume. If you go a bit longer than minimum listed you should be fine.

My Lyman manual has data for a 125gr HP for all the powders you listed.

124 gr PD over 4.1 gr Bullseye 1.12 COL is one of my favorite loads.

I am loading Berry 124 gr with 4.5 gr. HP38 with excellent results in my Glock 19 9MM

 

[MADDOG]

Thanks. I'll have to update my manuals. My Lymans 46th Edition doesn't list the HP. I looked on that Hodgdon site and it doesn't list the 124/125 HP either. There is quite a few FMJ though. Thanks again.

+1 on the 4.1 bullseye under 124 gr. plated Berrys.
I also use 5 gr Unique under the same Berrys bullet.
YMMV

I've been using Longshot for a very long time for 124 gr. JHP and 147 gr. JHP. I started in the mid range and still had plenty of room to work up from there. FYI, after I finished the work up I was in the middle of mid and max with 1100 fps.
HS6 has also worked well for me, but it isn't as effective with bullet weights beyond 115 gr..
Go to Hogdons loading pages and you'll find both of those powder charges there.

Bullseye, Unique, Clays, Universal Clays, Red Dot - all will give good results with 124 grain bullets, verify the load, but most of those seem to utilize somewhere between 4 and 5 grains

I know this is not on your list but I have been very happy with 124gr plated and
power pistol.

The Precision Delta 124gr JHP are jacketed. So I need data for the jacketed and not plated. Right? Also JHP data is different than FMJ. Right? I guess the OAL is really my unknown as most of the starting powder charges are in the same range.

 

[J_McLeod]

Yes, you need jacketed data, not plated. Both the FMJ and JHP are jacketed, so you can use the same data. Any 124/125 Jacketed data will work.

The major difference is is the OAL. Since I always use a turret or progressive, I try to set my OAL .010 above the load data to account for differences in the brass length. If you start with a low charge and watch for pressure signs, it should be fine.

Another Bullseye......Works great on the 124's

I doubt you'll have access to this powder, but 4.8 grains of VV N340 with a PD 124 JHP at 1.085" OAL runs 1,055 fps from my G17 and is easily one of the best loads from all of my guns.

 

[Marlin 45 carbine]

Red Dot is a low-flash powder also. but it spikes quickly, don't go past max

 

[gamestalker]

With the heavier bullets, which I would consider 124 gr. and up, I would steer clear of the faster burning powders. Load developement can get spikey real quick with fast burning powders, and heavier bullets. The 9mm is already a pressure sensitive cartridge as it is.

i load 4.3 and 4.5 Universal under a 124g MG JHP (mostly 4.3)... All my guns love that round. I just ordered 3700 more and gonna start loading them this week.

 

[Walkalong]

I doubt you'll have access to this powder, but 4.8 grains of VV N340

That is pretty light, but N340 is excellent with 124/125 Gr jacketed bullets in 9MM, especially in 3" barrels.

I chose HS-6 powder specifically for that application (Precision Delta JHP and Hornady XTP 124gr 9mm), and load them both to 1.090 OAL.

Have used Titegroup as well, but I definitely prefer HS-6 as its quite a bit slower and performs better than titegroup did.

 

[MtnCreek]

HP-6 is what you get when you dump the HS6 from your hopper into a can of HP38. Shaken; not stirred.

I also like HS6 w/ 124gr bullets.

The Precision Delta 124gr JHP are jacketed. So I need data for the jacketed and not plated. Right?

Correct. Use lead data only for lead bullets. Use jacketed data only for jacketed bullets. For plated bullets consult the manufacturer.

Also JHP data is different than FMJ. Right?

No, not really. Both bullets are jacketed, so their load data is going to be very, very close as long as they weigh the same. If they vary at all, it will be in their OAL.

I guess the OAL is really my unknown as most of the starting powder charges are in the same range.

Most test data is going to report OALs that are much shorter than you might actually use. That is to say, while the manual might quote a 1.070" OAL, your gun might prefer the longer, more practical OAL of 1.130" for better feeding. The rule is: You can always load longer.

Loading longer simply lowers the chamber pressure. This lower pressure will be made up when you do your incremental loads. In the end, you might end up with 0.1gr more powder. Beginning at the "starting load" and working up in incremental steps makes up for numerous tiny differences (bullet brand, nose type, barrel diameter, temperature, etc) from the load being reported in the manual.

Hope this helps!

Actually, all you need to swap "same weight and jacket-type" bullets is seating depth. If you know the seating depth for a 124 FMJ bullet and the "bullet length"you can use the oal and standard case length to find the seating depth.

If you seat a 124 JHP to the same depth as a 124 FMJ or 124 JFP and start at the low end of data, the pressures will be almost the same. If the 124 FMJ is .010" longer than the 124 JHP, seat the JHP to an oal .010" shorter than the FMJ oal. If you don't know the length of a specific bullet, ask other reloaders (more than one though- )

As rf wobbly said, a Longer OAL is ok as pressures will "decrease".

Documenting seating depth and bullet length in your reloading records, are useful for future load work-ups.

I've had great success using HS-6 under the 121grn JHP's I've been loading for my BHP. very accurate but the Hornaday's suggested starting load is not enough umph to cycle the slide for case ejection.
