[QUOTE="brian b, post: 76743, member: 2797"] this whole topic reminds me of an experience that I had a couple years ago, the very first custom gun that I ever had built was a 6mm Ack Imp with a 1-12" twist after several seasons my shooting habits changed as I realized that a hi B.C.bullet at 3000fps is far better long range medicine than a low B.C.bullet at 4000fps, so I started tinkering with bullets with a higher B.C. and found that the Lapua 90gr Scenar shot VERY well (it is supposed to have a 10" twist to stabilize). me and goodgrouper and 7mmrhb shot one weekend and everything was fine ,the next weekend we went back to the same spot only 20degrees colder with a hint of fog and every single bullet went through the target sideways, you can cheat twist a bit in 100degrees ,but the colder it gets the cheating stops. fiftydriver is correct in going with a faster twist to compensate for temperature and humidity and mother natures other forces.
