[QUOTE="rscott5028, post: 481118, member: 24624"] I've heard of exceptions where a gun with a slower than recommended twist will shoot fine with the longer bullets. But, that is certainly the exception. Invariably, it has always caused me grief and I've never been able to overcome slow twist with increased velocity to achieve best accuracy. Going from a 1:9" to a 1:10" twist has a much larger influence on the RPM than an extra 200-300 fps velocity. Choose your preferred bullet and get the proper twist, if you are interested in long range, you will want to err on the faster side. The barrel maker should be able to assist you. Also, the bullet maker will often have a recommendation as well. Berger recommends a 1:9 twist to stabilize the 180g VLD properly. Unless you are shooting benchrest competition where they need everything to be perfect for exactly one bullet, then it is better in my opinion to err towards a little too fast than too slow when using modern bullets in a hunting rifle.
