I should be receiving my new AP4 in .308 sometime next week. Now, I just need to find some good loads to try. Can anyone recommend powders for a 16" barrel? I plan on trying some of the really light bullets (110 V-Max), some of the 165/168gr, and 180's. Most of the load data that I found showed test barrels being around the 24" to 26" length. In that case, I would assume the slower burning powders would give the highest velocities. But what powders are faster burning that would be suitable for my gun? I don't need charge weights, just powders.
Any suggestions would be greatly appreciated. Thanks.
