[QUOTE="eshorebwhntr, post: 1101685, member: 17112"] I went on Berger's website and ran a quick calculation. I used 4000ft, 45F, 3100fps with the 168 Classic Hunter and your 11 twist. It put it right at being just barely stable enough with an SG value of 1.52 (1.5 recommended minimum). With the same parameters and the 168/180 VLD you get into the gray area of being unstable. If it's higher elevation, a faster MV, or warmer temp this will only help your case. Might be a nice compromise to accomplish what you're looking for. If you want to try a few of them shoot me a PM and I'll mail you some for a couple bucks. I've been playing with them out of my STW and they are doing pretty well so far. Shot a nice group with them at 300 this weekend in horrible conditions (wind and mirage) [/QUOTE]
