Just checking to see if anyone has a 9mm recipe using Win 231powder with Montana Gold 124gr bullets. I'm also using CCI primers. Please post OAL if you have it as well. I'm going to be using these rounds in a Beretta 92. Neither the Lee or Lyman manuals I have, show any recipes for this combo of components.

Tony, Hodgdon themselves, being the manufacturer of Win powders, list exact data for that combo on thier site. Always check the powder manufacturer, they all give out free load data for a lot of different bullet weights and styles.

124/125, same thing. You can extrapolate a starting OAL from any of of your load books for a JHP load then tailor to your chamber from there.

Use XTP load data. Dont use FMJ load data, because JHPs seat deeper.

Look at Regulator72's post. He had the exact same question.

 

4.5 and 4.8 grains of W231, 124 gr mg jhp, seated to 1.122

 

4.8 just a tad warmer. =)

No, they don't.

yeah, the MG JHP are almost RN. they are same as fmj

+1 I'm using 4.5gr with 124gr FMJ in a 92FS

If they are the same, then why is there seperate data for FMJs and JHPs? JHPs seat deeper due to the shape. The 124 JHP is a copy of the XTP profile, so it would only make sense to use XTP data which is different than the other data.

Not all JHP's are the same bullet shape. I have some old remington JHP's (longer) which are very close to FMJ. I believe the COL will be different depending on the bullet shape. A longer bullet will have a longer COL than a shorter bullet. The area inside the case under the bullet should be about the same. I'll have to look back in some of my loading manuals, but I thought I remember seeing same load values (or very close) for the same weight bullet, but COL was different.

 

You'll notice on the heavier weight bullets, the powder charge decreases because the bullet seats deeper in the case (area decreases).

Thats exactly why I said to use XTP data, because not all JHPs are the same nor FMJs

Thanks guys. Good info.

Cool! Thanks for the info. I worked up a few rounds with Bullseye powder and now want to try a few with 231 and see the difference.

I am running 4.2 w231, with MG 124 jhp. I am also using cci primers and my oal is 1.117-1.1175. I use it in my sigs with no issues. They are pretty light and I may bump them up.

Hey Bryan,

 

I loaded 4.5 grains of W231 with teh MG 124jhp, OAL 1.125 and it worked great for me in my Beretta 92. 4.8 grains was good too, but teh 4.5 grain loads were nicer I think.

in my book, it says that 4.5 is teh top end of teh load. 4.8 is over what my book says is max. I use 4.8 for my .40 rounds
