Re: Bullet Stabilization Questions
168...For the velocities a average 308 will drive a 168, its pretty hard to get them to go that far (1K). Try the 175 SMK, 155 Palma SMK, 155 Scenar, 190 SMK (for 11.25 twists or faster only), 155 AMAX, and the 178 AMAX. Those are all bullets that will make it that far in a 308.
The 175 SMK and 178 AMAX can be driven at 2450 FPS and still go staight at 1k. The 175 SMK and 178 can be saftly driven to about 2750 out of a 26" 12 twist 308.
The 155's can be driven up to around 3000 FPS (2900-2950 is average) and they have NO problem making it to 1200 and 1300 yards. Except the 155 AMAX. I would stop at 1000 with the 155 AMAX.
If you use the 168 at 1k you will only frustrate yourself. Depending on the conditions you are shooting them in, sometimes they will make it and sometimes they wont. That bullet was designed for 600 yard shooting. I can vouch for Sierra's claim that its not a 1k bullet.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
