I have found 2208 and W748 to be really good 308 powders, but lose velocity in shorter barrels compared to 2206H and H335.
2206H for the heavier projectiles (165/180) or H335 for the lighter projectiles (110/130) are about the best for a short 308, have to be careful with using H335 to get max velocity loads though, when you get close, it ramps up fast, assuming your rifle likes them, I would suggest the 110/130 TTSX as useful light projectiles out to 250 yds or so, and the 165 SST/168 Amax as useful heavy projectiles out to 600 or so (if you read the wind and range accurately) . The heavy projectile has the advantage of also being outstanding at close range on heavy or light framed animals, the tougher light projectiles get marginal at distance. My two cents worth!
