Hey guys,
because of a failed powder experiment Iīm having some Green Dot left.
And because it has such huge flakes which donīt drop consistantly in small cases, I thought I load it up in my .45 ACP.

Here are my datas, except the powder charge:

Boolit: 200gr. SWC H&G 68
C.O.L.: 1.26"
Crimp: light tapper
Primer: Magtech

What do you think, will Green Dot work in this caliber?

And if so, how many powder should I use for a pet load (disc-friendly)?

Alliant lists one load for Green Dot in the 45 ACP cartridge.

Green Dot has been around a long time and there is a lot of data for .45 ACP with the H&G 68 bullet. I load the H&G 68 bullet to 1.255" COL and don't have any problems dropping Green Dot with my Dillon 550, I don't know what (disc-friendly) means.

That are good news!

5.2 behind a 230gr. boolit, holy ****, I thought I would go with less in the beginning. 8-)

Hi ioon44,
with disc-friendly Iīve meant that it doesnīt hit to hard on the paper, a target or pet load like you might say.

Would you tell me how big your charge for the H&G 68 is?

I have shot a fair amount of Green Dot under cast 200 swc, H&G 68 style. My load came from some old load manuals so you will have to decide how to proceed. The best accuracy came in at 4.5 grains with my alloy around 14 brinell. I used Lee scoops and measured every load. Shot in a 1911. Recoil is about the same as Bullseye at 4.2/4.3. I think the accuracy is better with Green Dot, just a pain to scoop and weigh every charge. Please verify this info in a printed manual you trust.

I have an Alliant manual from 2001 which suggests 4.3 grains of green dot with a 200 grain cast boolit as a target load.
Pressures are very light, listed as 9.9Kpsi.
Velocity listed as 806 fps.

This shows a starting load Green Dot for a 200 gr swc. Lyman loading manuals are the best for cast bullets and Green Dot.

Thanks ABJ and tazman!

Well yes, the powder is a bit finicky in terms of consistant drops, right?
Iīve tried it some years ago in .40 S&W, but the charges were all over the place in my Dillon 650.
But the hole in the 45 powder funnel is wider, so I hope itīll work better.

QL says everything is comfy with your loads, too.

100% burnt powder, and so burning finish in the barrel, starts at 5.2grs what is more than Iīve expected.
But with 5.2gr. the "yellow" pressure zone in QL begins too.

So that will be my max. load, but I will start somewhat lower, with 4.4gr. I guess and look what happens.

A picture of your CZ97 would be nice. Are they still made?

But Master Tschofen comes into his years.
Idk how long he will built them from now on.

I've never used Green Dot, but I would assume the Alliant load is a max load. It sounds like 4.3 to 4.5 is a common charge. Keep in mind the 230 RN bullet has practically the same amount of bullet in the case as the 200 grain H&G 68 so the pressures and load data will be very similar.

4.8 grains under an MP clone of the H&G 68 worked pretty well in my Sig P 220.

Ran 27,000+ through my 1911 loaded with Green Dot. It meters well for me once I learned to put a baffle in my powder drops.
