When I could not get Varget I started stockpiling H4895 for SHTF. Those two powders handle my needs for .223, 30/30 and .308. H4895 has the advantage of being recommended for reduced loads and that was another factor is selecting it, as it would serve as a decent cast bullet option.
I have eliminated all my other rifle calibers (except for the .300 mag) as I found little use for them. KISS. I will likely get rid of the .300 Mag as well, even though it shoots extremely well.
