My .308 prefers H4895. Tried RL 15 and Varget, H4895 consistently shoots higher speed w/accuracy as well. I use Lapua brass and 45.5grs with 155gr Nosler and 41.5grs with 175 Sierra MK. My loads also jump .140 to the rifling. Standard Deviation is usually less than 10fps. Varget would get up to max, then velocity would slow down with some really flattened primers. If Lapua brass is 20grs heavier thats probably why I cant get more than 42grs of 4064 under 150gr bullet.
