I use Varget in my .308 loads. I have not had any trouble finding it the last few months and I have plenty on hand.

44.5 gr Varget (Not the fastest, but most accurate)
150 gr Nosler Ballistic Tip
Rem Brass
Fed 210 Primer
C.O.L.- 2.80

My hunting rifle in .308 is a sporterized Mauser 98 in a Butler Creek stock and Leupold 3x9 Vari X II. It will put 3 rds in .60" all day long at 100 yds
