[QUOTE="AKGuide, post: 907855, member: 64701"] Only time faster than a 10 twist is needed for a 30 cal is with the 240 smk if you cannot push it faster than 2900 fps you need a 9-9.5 twist. Also the cutting edge bullets in the 200 grain variety need at least a 9.5 twist to stabilize properly. My next barrel will be a 3 groove 9 twist. Just so I may shoot the heavy monometals like the cutting edge and also the 200 LRX without losing stability at long range. Reuben [/QUOTE]
