Welcome to THR.
Keep in mind that many 9mm bullets (lead, coated lead, plated, jacketed) can vary in weight from .5 gr to 1+ gr average so I interchanged load data for 124/125 bullet when referencing load data for my load development.
But if you insistt on using load data for 125 gr, go to - https://www.hodgdonreloading.com/reloading-data-center
Here are some examples using W231/HP-38 and ZIP, two comparable powders (NOTE: HAP for match shooting is same bullet as XTP without the expansion cuts ... Also note the linear progression of W231/HP-38 velocity related to powder charge between 124/125 load data):
And 124 gr load data for comparison:
- 9mm 125 gr Hornady HAP W231/HP-38 OAL 1.069" Start 2.8 gr (753 fps) - Max 3.3 gr (876 fps)
- 9mm 125 gr Sierra JHP ZIP OAL 1.035" Start 3.4 gr (886 fps) - Max 3.8 gr (970 fps)
- 9mm 124 gr Hornady XTP W231/HP-38 OAL 1.060" Start 3.7 gr (957 fps) - Max 4.2 gr (1,050 fps)
- 9mm 124 gr Hornady XTP ZIP OAL 1.060" Start 3.3 gr (888 fps) - Max 3.7 gr (967 fps)
And we are starting to see RMR specific load data.
- 9mm 124 gr RMR JHP Accurate No. 5 OAL 1.120" Start 5.5 gr (989 fps) - Max 6.1 gr (1,076 fps)
- 9mm 124 gr RMR JHP Ramshot True Blue OAL 1.120" Start 5.0 gr (992 fps) - Max 5.6 gr (1,084 fps)
The 125 grain HAP bullets I bought were .356. All the others are .355. That spooked me when I first started reloading 9mm. I loaded a few, took em outside and shot them. Most accurate load ever out of my Glock. But they seemed “different.” And since they were .001 bigger, I taped the bag up and put them away.
I’ll get back to them someday.
