Alright,

So its appears I made a bit of a rookie mistake and I need some help un screwing myself here.

I have a basic data for making 124gr 9mm bullets using the IMR 700X powder. I am really having trouble finding exact recipes using this powder. I was hoping someone on here has had some experince in using this powder for 9mm and could help me out with some data recipes.

I was also hoping someone can help me if they knew how many grains of powder were in a CC for the IMR 700X
 
I was using 4.7Gr of 700x for a 115Gr copper plated bullet 1.100" OAL which gave me about 960ft/s, which was higher than the recommended amount of powder on the hodgdon site. any lower than that and the glock wouldn't cycle properly.
the site says
Bullet Weight (Gr.) Manufacturer Powder Bullet Diam. C.O.L. Grs. Vel. (ft/s) Pressure Grs. Vel. (ft/s) Pressure
125 GR. LCN IMR 700-X .356" 1.125" 2.9 899 23,700 PSI 3.4 1003 31,600 PSI

work your way up from the bottom and see what cycles, I would recommend doing up 5 -10 bullets and trying them before going full out and doing 50.

as for cc, try a .66 disk for about 4.5 grains but verify with your scale. if you are using the lee loadmaster I find that it takes 2-3 throws before the powder is consistant in weight.
that is my recipe, your mileage may vary.

Midways LoadMap 9MM Series
Hornady 124 XTP-HP ( again, they tested with an overall length of 1.135")
shorter overall lengths increase pressure
Remington case--Win SP primer--universal receiver 4" barrel
IMR 700X powder start 3.2 grains-892fps-22800psi---3.4-936-25500psi
3.5-958-26800psi---3.6-981-28200psi---3.7-1003-29500psi---3.8-1025-30900psi. Start low and work up. Midways LoadMap showed loads up to a very Maximum of 4.3 at 35000psi but Don't go there especially if you shorten overall length. Be Careful!!! You see how pressure increases fast with this powder plus a shorter overall length would increase pressure a lot too.
Back in the late 1990's Midway published a series of LoadMap data manuals in 9MM, 45ACP, 357 Mag, and 44 Magnum. In the 9MM and 45 ACP manuals they tested for instance 10 different 124 grain bullets with 10 different powders. In 45 ACP they tested 14 different bullets with 10 powders. The only complaint is in 9MM and 45 ACP the overall lengths that they used are longer than bullet company recommended lengths, sometimes maximum length for the cartridge. In .357 and 44 Magnum lengths tested were standard seating lengths. They used different cases and primers in the different LoadMaps but the same case and primer for each caliber. For instance the 45ACP LoadMap used Rem cases and RP 2 1/2 primers in the whole manual. In my loads using Midway LoadMap data the loads in my pistols come very close to the results of Midways tests and I use the LoadMaps to compare data from other load manuals etc.

Thanks for the manual advice, will take it.

To help, I am using a Lee Pro 1000 press, if it helps any.

Again I am looking to use 124gr Hornady JHP XTP bullets.

Thanks for the info, it sure does build up quickly. I am looking to getr around 1000FPS, so I will start at around 3.5grns.

Now do you happen to know what that is in CCs?

try a .46 I was getting about 3.3-3.5 from that. give it a couple throws and then weigh, should come in around there.
 
If you go to the Lee website and look under instructions you will find the VMD (Volumetric Density) for most powders.
If you use the available date for 125 gr jacketed bullets you will find IMR 700-X listed as 3.0 - 3.6 gr.
Using the VMD of .13430 the volume in cc's would be 3.0 x .13430 = .40 cc
similarly 3.6 gr would be 3.6 x .13430 = .48 cc
powder disks .40..43 .46 and .49 would be in the appropriate range.

To be honest, being new I didnt want to buy bulk, and thats all the local store had. Next time it will be Berrys bullets.

go to gunco. he can bring them in without a shipping charge if you are willing to wait for his orders to come in. usually see what you need in a couple weeks.
