Anyone try superformance in a .308 yet? I picked the forums brain if you will on a lighter weight (sub 150gr) 308 win load to get more velocity and now im wondering about using superformance powder. I’ve got a couple pounds of it but have never tried it yet. It’s also available quite a bit compared to other powders.
I’ve got 9 lbs of Varget also. Should i just stick with that?

First off, that powder is not what Hornady uses in their Superformance ammo. They use a blend of a fast burning powder and a slow burning.

Superformance powder is going to be too slow burning for most loads with a 308. You just won’t get very good speeds before maxing out on case capacity.

The powders in the black boxes are the ones that tend to work best in the 308. Superformance is pointed out with the red arrow, and you can see it’s well outside the ideal burn rate.

IMR 4166, Varget, RL15.5, RL-16, etc are the best in regards to temp stability and most bullet weights. IMR 8208 is good for lighter bullets.

If you have 9# of Varget I’d stick with it!
I’ve had good luck with IMR4064 as well as BLC/2. 4064 seems to do a good job from 130-168gr, varget from 148-190gr

I am a big fan of varget but I have gotten excellent accuracy and excellent velocity with CFE-223. Three 308s are all turning in 3/4s or better and 2805+ plus with 168s ~47.0.

Superformance is a special powder used by Hornady. Make sure you know what you are doing. I
If you could find H-4895 (the original US Powder for the 7.62 Nato or .308,
Varget works, have not tried CFE-223, but heard good things. Can't find any data on H-4350 especially that it works in .243, .260, 7mm-08 -308 cases.

The powder Hornady uses in their Superformance ammo is not the same as the Hodgdon labeled Superformance powder, just fyi.
