Unable to get the data from the Lehigh Defence website. I need .45 ACP standard pressure loads for the 170 gr. May use them in the N frame ('37 Brazilian 2.25" barrel) as well as a couple 1911s. Anyone have standard pressure loads? Thanks for your time. Packy

Not scripture but it will get you there:

Cartridge : .45 Auto (ACP) (CIP)
Bullet : .451, 185, Barnes TAC-XP 45108
Useable Case Capaci: 9.110 grain H2O = 0.591 cm³
Cartridge O.A.L. L6: 1.275 inch = 32.39 mm
Barrel Length : 2.3 inch = 57.2 mm
Powder : Alliant RED DOT

Predicted data by increasing and decreasing the given charge,
incremented in steps of 2,0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

There is load data on their website perfectly available: https://cdn.shopify.com/s/file...olled_Fracturing.pdf

In my pistol, I use 1.236 COAL instead of 1.230 listed in their manual and Vectan SP2 powder.

I can't open the data page on my computer for some reason. That's why I asked. I need something like 231 or something common in the US. Thanks for the data though.

Here is a screenshot from their "data page":

Thanks. When I click on the ACP loads it comes up with a blank screen.

Any Unique loads?

No,

that is all they published. But can be simulated in QuickLoad easy:



1.23 COAL, simulated for 5" barrel:

5gr - 12204 PSI - 855 fps
5.5gr - 14730 PSI - 932 fps
6gr - 17660 PSI - 1007 fps
6.4gr - 20324 PSI - 1066 fps

But this is SIMULATION ONLY. No guarantee!
Start low, work up and use chrono.

Are these frangible bullets? If so, don't use loading data for ANY jacketed or plated bullet. Don't believe you can use data for monolithic bullets (all copper) either. Thus, use data from manufacturer.
Richard Lee's #2 manual has data for frangible bullets.

If you spend 30 seconds with google, you will find these are monolithic copper bullets. Finding your post absolutely useless.

Of course I reload these bullets and many others for a while and compare QL calculations with real world data.
