Okey boys and girls here we go. I have a Remington 700 BDL in 25-06...blue and wood. I've had it for quite a few years and it has served well in taking a few Dall sheep and gotten out with but a small scratch on the stock. It has since been retired from serious use due to it's successful service in harsh conditions. I want to rebarrel it now and use it as a dedicated coyote/wolf rig. I'm going to put a 26" tube on it and plan on shooting bullets in the 80-100 grain range. Question is, what is the preferred twist rate for the given bullet weight? Another question is this: Would there be a decisive advantage to going with a 25-06 AI? Thanks in advance for any input.
