I only use Varget in my M1. I tried all the others and had the best luck with it. It fits snugly in with 4064 and 4895 for burn rate. While mine is a 30-06, I have a friend with a 308 who also uses Varget almost exclusively. We both use 168 BTHP's for our regular match loads, and I use Barnes 175 Match Burners for my longer range match loads which closely replicates the original match loadings. I have also used 190 BTHP with the slower burning H4350 with very good success out to 800 meters, but the 175's do just fine out at that distance as well. H4350 is generally too slow with the lighter bullets in 308 especially.
Definitely recommend Varget for the Garand!
