I load for:
.223
.22-250
.243
.6.5X55 Swede
.308 Win
.30-06
IMR -3031 shoots from tack driver in .223, .22-250, and .308 to good in everything else. I use Re-22 in the Swede because it gives me the best accuracy. If I could only have one powder it would be IMR-3031.
P.S.ArchAngelCD, I found load data for all the calibers you listed using IMR-3031. Don't know how it will shoot for your rifles. Good Luck.
