Need help with green dot load data for 10mm 160 grain cast boolits

[Tripplebeards]

Got help from a few members here on 180 grain cast and 10mm. I was given load data up to 6.2 grains. I tried 5.8 grains of green dot with 180 grain AMEC boolits and it cycles great. Well, project number two. Just casted up some HPs out of our group buy .402 170 mold. With the deep HP cavity average around 160 grains. I still have almost 8 pounds of greendot I would like to use. I am guessing I can load a hair more powder than the 180 grainers. Hoping someone can run some data for my on load data again. Thanks for the help. I also have less than a pound of HS-6 to try.

Anybody get a chance to plug a 160 grain boolit into load data with green dot?

Any truth to this? I’ve been trying to do research myself since I can’t find any load data and it says that green that is basically the same burn rate is HP 38? If so I’m guessing I can use the same load data as HP38?

If so my boolits average weight is 158.0-159.0…

So it says 6.5-7.3 grains with HP-38

Looks like the powders are more spaced out on the burnt rate chart listed here…

I plan on checking the overall seating depth of the 180s in the ACME boolits and see how much The case capacity varies when the power points above or seated versus them.

Looking at load data at https://shootersreference.com/reloadingdata/10-mm-auto/ left me scratching my head for something close.

I ran the following through Quickload. My seating depth and barrel length were wild guess values. QL runs are much more accurate with correct seating depth (inputs are AOL & bullet length) and barrel length.



Cartridge : 10 mm Auto (SAAMI)
Bullet : .400, 175, LYM LFN 401638, weight reduced to 160 gr
Useable Case Capaci: 15.000 grain H2O = 0.974 cm³
Cartridge O.A.L. L6: 1.250 inch = 31.75 mm (0.327" seating depth)
Barrel Length : 5.0 inch = 127.0 mm
Powder : Alliant GREEN DOT
