Kinda unchartered waters finding Green Dot lead data for .40 S&W.
2002 Alliant data says 5.3 Green Dot is MAX with a 180 Jacketed bullet.
Treading water backward to Red Dot shows 0.3 grain less, or 5.0.
So, I would call 5.0 Green Dot Max with your 180 lead bullet & Green Dot, and call it good.
Reduce 10% for a Starting load of 4.5 and work up.
And do so at your own risk.
Thats just a WAG on my part.

Disclaimer: Use the following load data information at your own risk.
Maybe the 2004 Alliant load data (glarp.atk.com/2004/2004Catalogs/2004AlliantPowderSM.pdf) may help. During the last shortage, I tested Green Dot and found I needed to use .2-.3 gr more than W231/HP-38 loads to produce comparable loads. I used 4.0 gr of Green Dot as start charge for 180 gr lead TCFP (MBC IDP #5) and worked up to 4.8 gr.

I've tested a lot of lead bullets in my .40, with a lot of different powders, but I've been quite luckey with Green Dot. It shoots to the right spot, and fast enough to get the job done.
I took 2nd in the Nevada State Steel Challenge last year, during my first year with my new Tanfoglio Limited. I used Lee 175gr TC sized .403" from WW+2%tin with BAC lube and 4.8gr of GD for 1010fps from my 5" barrel.
You didn't mention what gun you're using, so we could reccomend better, but that'll get you started.
