Need help from Rocky Raab

375H&H

or from 20gabob , I'm looking for some load data for the 45 ACP & 38 special using ( here's where it gets tricky ) W-230P

230 gr FMJ & JHP for the ACP and 158 gr lead in the 38 .

I did a search and only came up with one thread that talked about this powder , but it failed to provide any data info .
( I did bring the thread back to life though hoping someone else may see it and add some info )

One other question I have , while searching for info about this powder ,I'm seeing it referred to as " win 230 " and as " win 230p "
Are these two different powders , or just two ways to refer to it ?

BTW , if I'm lucky enough to get data for this powder , it's only going to be used for plinking ammo .

Present, sir!

I don't load for the .45 ACP, but I have used W230P. According to my tests, W230P is slightly slower than Bullseye or RedDot, being close to GreenDot in burn rate. It is definitely faster than Unique or Universal. You can comfortably use Bullseye or RedDot DATA with W230P.

Here's my carefully thought-out method for loading "mystery" handgun powder:

Load two or three rounds of .38 Special using Bullseye data. Shoot in a strong .357 Mag revolver. If the velocity is faster than what Bullseye would have given, I do not use the powder at all. If the velocity is about what Bullseye would give, I use Bullseye data with that powder.

If the velocity is significantly slower, I load three more test rounds using Unique data. Again, judge the apparent burn rate by the velocity achieved compared to what Unique would give.

If velocity is still low, repeat using data for 2400 powder.

Finally, label the can of mystery powder with a sticker: "Load using ______ data."

From my Hornady Vol. II.

Start load for 230 is listed at 5.4 gr with a 230 gr. FMJ. I would start at 5 and work up. (pp. 357)

They do not have a 230 load for the 158 gr. lead RN bullet. But for the 158 jacketed they have 4.2 gr. to start. All other powders listed for both lead RN and JHP have one grain reduced to start with the lead bullet from the jacketed bullet. So, I recommend starting at 3.2-3.5 gr. in the .38 Special with a 158 gr. lead bullet. (pp. 340-341).

These are starting loads.

Speer 's # 9 reloading manual does not have a 230 fmj load using 230 powder, BUT it does have one using a 225 gr. Speer jhp with a start load of 4.7 gr for 780 fps with a maximum load of 5.1 gr for 844 fps.
I would think that it might be prudent to start at the low end and see how it goes.
Never used 230 powder, so I don't know anything about it's quirks,
be safe

Thanks for that info , Im going to load a clip full for the ACP and see how they work . I'll start at 5 gr's or slightly less ( 4.7 or 4.8 ) using a 230 gr bullet .

I just want to load some plinking rounds for the S&W 4506 and hate having 2 lbs of powder just sitting around taking up shelf space .

Thanks again
