with Alliant poweders being scarce/expensive-is there an alternative 308 double based powder for some extra FPS for things like juggernauts/175+ 308 (winchester) bullets.

2000 MR alternative

CFE 223 works well in .308 with 175’s. Getting around 2550 fps in 16 inch semi-autos. 2630 fps in 20 inch bolt guns. That’s with 45 grains in LC brass. Could probably go a bit higher but it shoots well as is. I think hodgdons data tops out at around 47 grains in Winchester brass.
I've shot a bit of 2000 MR in the 308 Win. with 175's. I also tested CFE 223 and found it to be very close to 2000 MR in charge weight and velocity. When I run out of 2000 MR and can't find any, I will be using CFE 223.
