? 9mm load with 147 gr cast bullet?

[H Richard]

I normally have been reloading 125 gr RNL cast bullet using 3.8 gr 231. I get good accuracy and functionality with it.

I am interested in trying some 147 gr. loads. My cast bullet supplier included a generous sample of 147 RNL cast bullets in my last shipment of 125 gr. I have been looking in my manuals, and on various reloading sites, and don't seem to find much information. I did find one load of 4.0 gr 231 with the 147 gr cast, which sounds like it might be a little hot.

Can anyone recommend a good accurate load that is hot enough to reliably function most semi-auto's without getting to +P pressures? I'm looking for a target & plinking load, not a defensive load.

Thanks

I'l check my notes later to make sure I remember correctly, but I've been using the Missouri bullets 147 TC bullet over 3.5 grains of 231. Very consistent 900 fps from my M&P 9mm.

 

[H Richard]

Thanks. Sounds logical, What do you set the OAL at? Assume you have no problems with generating enough pressure for reliable functioning. 900 sounds like a comfortable load, I'm not looking for a top end defense load, but an accurate one for informal competition and plinking.

Good morning
I was shooting a 145 gr Rn in my 439 for some time.
Used 3.8 - 4 grains Unique. I would start at 3.5 and load 5. It will all depend on your recoil spring. My old 439 was a an ex-Police carried tool then my every day shooter as my sons were growing up so it is well shot. Has been idle some years as we graduated to the caliber 45.
Interseting though how many US calibers slowly gravitate to Very old loadings. This sounds just like a 38 Special load I carry daily in my 5 shot.

The W-W 14th Edition reloading manula lists the following data for 147 gr. lead cast in 9mm:
3.3 gr. W-231 = 865 fps = 29000 psi
3.5 gr. W-231 = 905 fps = 32100 psiMAX load
I used the 3.5gr. W-231 when I shot lead bullets in 9mm.

Yep, 3.3 gr 231 under a Missouri 147gr lead TC works well in all 3 of my 9's.

3.5gr of Bullseye and 3.8gr of Green Dot works great in my 9mm 1911.

Thanks for the loads guy's. Since 231 is one of my "go to" powders for .45 & .38 I'll mostly concentrate with it. I loaded 20 rounds to start at 3.5 gr 231, and extended the seating depth to an OAL of 1.130" I seat my 125gr to 1.115". That's only .015" more, and I possibly should allow more room in the combustion chamber. The difference in the bullet length is .050" (.680 on the 147 to .630 on the 125). But backing the charge off .3 gr. should cover it. I'll be out to chronograph both loads hopefully this week.

I once stumbled into a 'deal' on 147 gr. Magnus RNFP. The first thousand I loaded up with dozens of recipes. The last nine thousand were seated over 3.4 grs. of 231.

Worked great in my 3913 and STI Trojan with factory springs.

Sure wish I could score another 10,000 of these at $40 per K.

This was a very accurate load out of the 1911 STI.

are you referring to these slugs? they look like excellant paper cutters and would want to try these out to 50 yds PPC.
