[QUOTE="wnroscoe, post: 168134, member: 6698"] I had SG&Y build a 300 Jarret for me several years ago, I wanted a 10 twist but Speedy talked me into a 12. My bad for listening. When it's in the 90's it'll shoot the 190 SMK's but, when it cools off, during hunting season, the accuracy goes away. I've been able to shoot the 175 SMK's in the 90's and 50's just fine, 1/4 MOA to 330 yards. A friend of mine had Terry Cross build him a 300 RUM with a 10 twist, his rifle shoots everything up to the 210 VLD's like a house a fire. The Jarret and RUM are pretty close ballisticly but, I should have built a 10 twist to shoot the heavier bullets. I would strongly suggest that you choose the 10 also unless you’re only shooting the lighter bullets. My 175's are being shot at 3,415 fps, the RUM that my friend has is shooting the 210's at around 3,250 fps. I think that’s a much better choice. Just my .02 worth, good luck. [/QUOTE]
