[QUOTE="diggler1833, post: 3629697, member: 48072"] The 165gr SST is right in the ideal length range for a 1:12" twist. That twist should have no problem stabilizing bullets in the 130 - 180gr range. For many years the M40 series of sniper rifles used by Marines shot a 175gr SMK out of a 1:12" twist. Varget is one of "the" powders for the .308. Very few rifles will shoot Varget poorly and another powder much better. I have zero experience with SIG brass, so I have zero clue about case capacity...but as long as you start a few grains below max charge as recommended by Hodgdon, you shouldn't blow your face off. as a matter of fact, I am going to bet that between 43.0 - 44.0gr Varget, you'll find your sweet spot. That happens about 80 percent of the time with guys and the 168gr SMK. I have a few .308s that I have 165gr Nosler BT loads for; one is a hammer at 43.0, the other at 43.5gr Varget. One of your biggest accuracy factors will be bullet jump with the secant ogive of the SST. You can play with charge weights or jump first, I always did jump testing first. Load a few rounds at .010, .040, .070, and .100" off the lands, and I'm sure you'll see a preference for jump in your groups. From there I play with charge weights. If you don't have the $40 seating depth guage from Hornady, I'd consider it a worthwhile investment. [/QUOTE]
