What powder would it be? I know one powder is not always the absolute best, but a good all around powder for general shooting of these calibers. No super long distance or benchrest competition. Both bolt and semi auto (AR)Leaning more to use in the 223/556
Probably 55 gr bullets in 223/556 and 150-168 gr in the 308. Anything other than VARGET as it is impossible to find.
Sorta like Unique or HP 38 will work well in most handguns.
I posted this on another forum so trying to get a broader result.
