As usual I got sucked into no hazmat sale at
https://www.natchezss.com.
I have a big problem with purchasing new powders that i havent tried yet. I just like to play around with different powders so I keep buying new ones all the time. This time i found Vectan powders on sale for about $14.50 for 0.5kg or roughly 1.1lb so i ordered 4 bottles. Ends up being around $13/lb so you cant beat that price considering my local Bass Pro is selling Hodgon at $30+ /lb.
Now the only problem is load data. These are actually two different powders from two different factories one Italian on French. GM3 is fine grain powder with burn rate around HP38 while A0 is a flake powder with slower burn rate around Herco/Longshot.
My plan is to use GM3 in 9mm and go from there maybe some 38S, 40SW, 45acp. Sounds like i should be able to start around 3.5gr and go up from there to I'm guessing around 4gr which is my HP38 load.
A0 I want to use in 357Mag and 10mm to start. I'm not sure where my starting load for these should be just yet.
Yes I googled and i have their official Vectan load data PDF but GM3 is listed as shotgun powder so no official handgun load data but i see many positive reviews just not much load data.
If anyone can help me with starting loads for these i would appreciate the help since these are new to me.
