I got a mold for 125 gr 9mm and I have alot of 231. Will I be able to get a accurate load with this combo?

[depoloni]

Yep. My personal favorite for bulk, mild-to-medium plinking/practice loads.

Give 4.0-4.2 grains a try, a little hotter up towards 4.5 if you need to to cycle your pistol, you'll likely get good results. That said I use an OAL of 1.125" with the aforementioned 4.0-4.2. Longer will mean less pressure, shorter will make things hotter.

What LRN bullet specifically will you be casting?

And, in case you didn't know, HP-38 and Winchester 231 are exactly the same powder.

Edit: You're shooting them through a normally-rifled, not polygonally rifled, barrel yes?

I have sh0ot thousands of 125 gr. LRN with 4.2. No problems with any aspect (cycles, accuracyu asnd no high pressures).

W-231 works very well with lead in 9MM.

Yes, it's a good combination. But (if it matters to you) you can get higher velocities at lower pressures by using similar charge weights of Bullseye.

[Walkalong]

WSF is lead friendly, and will push them along quite well too, if you are looking for some velocity.

in my ruger p95 im running 4.4 grns of W231 with a COL of 1.165 at around 1000fps. started around 3.6 or 3.7 and had cycle problems worked up and to 4.6 and didnt like them droped down to 4.4 and after a k or better working fine.( like said before this works in my gun.)

The bullets are cast in a Lee mold, and I am shooting a CZ P07. Thanks for the info.
