Thread: Powder recommendations for short barrel 308?

This means use 2208 or 2206H. Either will work well. I use 2208 in my .308 for what its worth.

I guess looking at the Hodgdon reloading data for 308 pistol (15" barrel) shows that. And probably a better place to be looking for 16" barrel data than the rifle data (based on 24" barrel?).. still 2206h (same as H4895 or 2208 (same as Varget) seem to offer the best of that lot, and Win 748 is also supposed to be good - its what Winchester use for their 308 loads after all!

Hence my suggestion at the beginning of this thread....
