hey guys , well here is my issue im reloading 9mm ammo for my SORINGFIELD XDM 9MM im using campro 147gr projectiles federal small pistol primers and 2.9grs of IMR 700X ( which shows as the max load)
and an OAL of 1.100 and the bullet flys nice but it wont eject the spent round it stoves pipes every round i checked the extractor its good, gun is clean

i would like to know if anybody has a load for these that might work better? thank you
 
I used w231 3.5 gr at 1.111 OAL

Everything else is the same for you

Worked fine in a glock 17, m&p pro and a np34

Have you tried this load in another gun?
 
Change your recoil spring to a lighter spring. Your bullet is moving slower then a 124 so a lot less energy. Remember energy is the square of your velocity so changing your velocity by 300 fps changes your energy by a factor of 90,000.
 
+1 on Walter`s comment......chnege the recoil spring, or.......change the powder......I use 3.4 of Titegroup with 147 CamPros with no issues.....cnock-cnock-cnock ;)

Yes I tried it in a glock 17 gen 3 and a beretta PX4

Worked fine I. Those but not the SA xdm

The 124s worked fine

Changing powder really isn't an option I got 60lbs of the stuff
 
Try Wolff springs. They offer tuning kits for popular guns with a selection of different weights of recoil springs. You can choose the spring that works best for your ammo.
 
"...shows as the max load..." Did you work up to that or just pick it and hope?
"...stoves pipes every round..." What's it do with factory ammo?
 
look for any signs of over pressure, and slowly build up 0.1 grains at a time. I use 4.7 grains of unique under a 124 grain and my lyman manual shows 5.0 grains as maximum, but under alliants website they claim 5.8 grains is maximum which is a pretty big difference. Point is 2.9 may not be the absolute maximum, very slowly and carefully build up a bit
 
The Hodgdon's data shows a maximum of 2.9 grains of 700x at 32,000 psi with a jacketed Hornady bullet.

Max pressure for the 9mm is 35,000 psi and +P 9mm is 38,500 psi, the lower pressure at the Hodgdons site is due to unsupported Glock barrels.

By seating your bullets out further you will have lower chamber pressure and remember max OAL is 1.169 and your pistol will tell you what it likes. If seating your bullets out further and adding more powder won't cycle the slide then all that is left is spring rates.

Below is a good write up on setting your OAL, also at the Brian Enos forum the competitive shooters like heavy bullets and fast powders. Just remember the object is lower pressures and fast recovery time for faster shooting and your near the top of the pressure limits.

With my Quickload software program I do not list 700x powder, but by using Bullseye powder and going from 1.100 OAL to 1.130 dropped the pressure 3,200 psi and 1.169 the chamber pressure dropped 7,000 psi with the same load of powder.

I took that according to the hogdons website and the pistols work fine with factory ammo and the 124gr but not the 147

At 2.9 give or take .1 of a grain there is no signs of flow in the primers

That's because you are no where near max.
My data for 700X shows 2.8gr for starting load and 3.6gr max(30,700 cup) for 147's.
 
take the barrel off and chamber the bullet. it should be a little sloppy. If its tight then you didnt re-size properly. I had this happen to me when i setup the die on my single stage LNL. I then popped it out and threw it in the LNL AP. My presses arent even close to the same standoff. They worked in my HK USP 9 but wouldnt eject in my M&P 9.

Yes I realized when I decided to check the Lyman book I had burried under some gun magazines
2.8 start and 3.6 max at a OAL of 1.115

Thank you for all your help every body

This is why I hate having to change powders I'm not a big fan of change
 
If you look further you will see the Hodgdon's data is for a jacketed Hornady bullet and the Lyman data is for a Speer TMJ bullet which is a plated bullet like you are using. The lyman data is also from a universal reciever and test barrel meaning the chamber and bore are minimum SAAMI dimensions which would raise pressures. Meaning there is a very good chance you will have "lower" pressures in your pistol.

The ratio
125gr * (1500 fps)^2 : 147 gr * (1200 fps)^2 = 1.33 : 1, i.e. an increase in energy of one third.

it would take a compensator on the gun to shoot a 124GR bullet @ 1500FPS... and a good recoil spring !

Yes, those numbers are high; I just grabbed them out of thin air because it made the arithmatic easier. Now, take 1200 and 900 fps, the ratio is a bit higher, 1.5 : 1, or about 50% increase. My point being that the increase in bullet energy is substantial but not astronomical.
