We have only a few places to buy powder up here. I have 3 calibers that I will be concentrating on reloading. In .308 bolt, LR with 26in barrel using 178gr Amax and hunting with 22in barrell 150gr or 168gr. In 6.5CM will be both gas 18in and bolt, 129gr SST and 140gr. In .223 all gas at this time tactical 16", then 2 with 18" and 1 with 20" barrels .45gr Vmax, 50 and 55gr Varmegeddon, then 55gr FMJ, 62gr and 77gr. My question is what other powders work well in these calibers.
At this time I'm using for .223 Win 784 and BL-C(2). 6.5 CM H4350. .308 IMR 8208xbr. Wht else will work well in these calibers?
