I’m looking for True Blue load recommendations for .45 ACP:
- 230 gr HC (hard cast) RN and
- 185 gr HC SWC.
Low end of the +P range would be nice.
Based on what I could find from the Hodgdon’s website and Handlloader magazine:
230 gr HC RN: 7.2 - 8.4 gr True Blue
185 gr HC SWC: 8.8 - 9.2 gr True Blue
Does that seem reasonable?
231 is never a bad choice in .45 acp.

I chose True Blue because it’s always done well for me (performance wise) and it meters so damn well because it’s so fine grained.
I'm a big Unique or Bullseye fan.
But it wants to be accurate, and about anything in the listed data will do well.
Ramshot says 6.7-7.4 for your 230 cast bullet and 8.5-9.4 for the 185gr bullet. I load the 230 cast bullet with 7gr True Blue. Works wellQuote:

Lyman’s #49 gives a max charge of 7.0 grains under the 225 gr 452374, for 884 fps. Take that as a caution and work your loads up from somewhere safe.

True Blue is my main powder for the .45 ACP. It burns clean at the top end of .45 ACP pressures, and gives single digit SD numbers, if that matters to you.

How long is your HC bullet and what is your OACL?

This is reload data from Handloader magazine for hard cast RN 230 gr bullets: 7.2 - 8.4.
I'M with WingerEd on using Bullseye or Unique in .45 ACP, but I cannot imagine why True Blue wouldn't work perfectly well. Given the velocities vs. charge weights, True Blue appears to burn faster than, but otherwise similar to Alliant Blue Dot (hence the name, perhaps?). There are more economical propellants with which you can obtain your desired performance, but if you are particularly comfortable and experienced with the use of True Blue, it makes great sense to stick with what you know.
Unless one is trying to do something very unusual with the .45 ACP, almost any shotgun/pistol propellant with a burning rate between Alliant Bullseye and AA#7 (including those) will work very well in the cartridge. One must decide at what point they are willing to sacrifice a bit of performance for greater economy, or the converse.
OP asked for True Blue Data. I agree BE, Unique, or even Red Dot would work great - and do for me. He's looking for True Blue, and that is what he is comfortable with.
Here you go: https://www.lhs-germany.de/fileadmin...dition_4.5.pdf
For 230gr Lead: 6.7gr - 7.4gr (822fps - 913fps)
For 180gr Lead: 7.7gr - 8.5gr (947fps - 1052fps)
For the 185gr, I'd probably reduce to 7.5gr - 8.0gr.
Either way, you'll likely find a load that works in that range.
I am a bit less picky with pistol loads and especially the .45acp. I have always used whatever powders I could find on the shelf. Red Dot, Green Dot, Blue Dot, Unique, 231, AA5, AA7, etc, etc. Once I got my progressive press I 'migrated' to the fine grain powders that would meter better through the powder measure. My measure for pistols is the Lee disk. I don't really care what powder it is as long as I can find a book load for it.
When picking a load I find the max charge and then pick the disk closest under max, usually a few tenths. Above the halfway point on the book min-max range. Then go shoot. And, yes, I do check the load thrown by the powder measure, about every 10 cartridges.
PS if you shoot competition ignore all this :) Fine accuracy needs more consistency in loads.
The exact bullet matters, especially when you’re going after +P charges. Are you using that Oregon Trails bullet?Quote:

I want to stay in the low to mid range +P loads.
The reason I’m focusing on True Blue is because it meters extremely well, I have 5 lbs, and my son-in-law uses it with his Ruger 1911 with good results.
I’m loading for a S&W model 25-14 wheelgun with a 3” barrel. It was manufactured in 2007, so it’s a modern gun designed for +P loads.
Using hard cast RN bullets from Space Coast Bullets in Melbourne, FL. They offer an excellent product. The only difference I could imagine that might make a difference is BHN. Space Coast hard cast bullets have a BHN=18.
One other thing. I found this in the Western Powder load data pdf:

This is for 45 ACP. The LC SWC 180 gr entry is the one of interest. That COL=1.267” seems shallow?
jmho - 4.5 to 5.0 grains of red dot under a 230 gr. hard cast bullet will do anything that the other powders listed + using 1/2 the amount of powder -
That's 45 auto rim load data.Quote:

But I am loading for a S&W 25-14 wheelgun using Starline 45 ACP +P brass. That data should apply.
That one has a long nose on it. Probably over .6 long.Quote:
