Load Recommendations for 9mm 147gr.

i have been trying to work up some loads for my springfield 5.25 for IDPA matches. i have been shooting 124's for a long time, but i have been convinced to try the 147's. Does anyone have any load recommendations? i typically load my 124's with N320, and i loaded a few test rounds with the 147's over 3.3grains of N320 @ about 927FPS. I got some slightly flattened and cratered primers.... If these were self defense loads i would be good with it, but i intend to shoot hundreds of these a month. So if anyone has any pet 9mm loads with 147gr projectiles, i would appreciate the input.

Mixed cases, WSP primers, OAL 1.145

Montana Gold 147 CMJ, 3.7 gr N320
Bayou poly coated 147, 3.4 gr N320

Either runs 129-134 Power factor in 3 G17's, 2 1911 9mm's, 2 CZ-75's and a M&P Pro.
I even use the MG bullet version in my AR9 PCC---runs 100% at around 131 PF.

YMMV, "Professional driver on closed course". "Do not try this at home" etc. etc.
 
Bill, do you notice any velocity difference on the poly coated bullets? I won 1,000 rounds of coated bayou bullets some time ago at a small competition, but i have not loaded a single one. I had so many berry's 124's on hand thats what i have been loading.

All other things being equal, the coated bullets are faster than jacketed. Have not compared them to plated, but would suspect the difference might be less.


3.7 N320 with a MG 147 and 3.4 N320 with a Bayou coated 147 delivered the same velocity.

What bullet and OAL are you trying with 147's? I'm a bit surprised you are getting
143 PF and pressure signs at 3.3 gr N320.
 
the desired OAL that i load to is 1.145. the OAL variation on my dillion with mixed brass ranges from 1.139-1.149. I fired them through my M&P shield also with similar pressure signs. I just wanted to make sure it wasnt an issue with the barrel dimensions on the springfield. now from what i saw, the flattening of the primers was slight along with the cratering. i was actually just wondering if my "crimp" is too tight. I left my maching set up just like i had it for the 124's, and loaded the test rounds with the 147's. the only adjustment was for the powder charge, but i did notice that the bell on the cases didnt hold the 147's without me holding the bullet on the case when i seat them. I did pull one, before firing any, just to make sure it didnt deform the copper plating, and it was good no scratches or dents. i checked powder weight on every other round when loading test rounds and all were 3.3-3.4grains. i guess the bigger variables i have with the dillion is the OAL... I cant seem to get that tolerance gap to close any. I dont know how much of a difference .010" makes on pressure in 9mm, but thats also something i was considering.
 
972 fps with a 147 is a power factor of 142.9. That's plenty hot, especially with a powder as fast as N320. Try dialing it back to 130-132 PF. That's just under 900
fps. If you want to stay that hot, try N340. Still a bit baffled about the 972 fps with
a 3.3 charge weight--
 
I read that the only adjustment you made was powder charge. Did you check OAL ?

972 is really fast for a 147.

The chart shows 3.3 for a 145 RN Max for 915 fps.

You are there.

Can't get it format.


Max charge for 147 XTP is 3.9 for 978 fps.

Go for a slower powder for the 147 great bullet.
