[QUOTE="Greyfox, post: 679148, member: 10291"] A lot have good points have been made. Something else to consider, particularly since you are speaking about 1000+ yards, is the 168 SMK. The bullet design, while sufficient for 700 yard work, is not the best design for the longer ranges due to the bullet profile, particularly the boat tail. This is pointed out in Litz's book. For the longer ranges I think you should go with the 175 SMK, or try one of the VLD designs. Not only will the be more stable/accurate, but as you point out, due to the higher BC, will catch up with the lower BC bullet at long range. Since you have a supply, if need be, they would sell quickly on this site, they are a great mid range bullet. I personally set an accuracy goal of .5 MOA or better, with much of my final testing done at a 500 yard range after initial results at 100/200 yards. I get best results with 43 gr. of Varget with 175's at 2550 FPS out of my MilSpec. 2700 FPS with 44gr of Varget with 168 gr. Both shoot .5 MOA or better with and ES of 5-15 FPS.
