I'm a new member here and have searched many topics on these calibers. Hopefully you can provide some good info on these to help make my decision easier. I'm rebarreling my #1 with a Pac-Nor barrel. It's currently a .243. I've narrowed it down to the 2 listed. I'm 90% using it for varmints and will be shooting 75 or 87gr V-max's depending on which one I pick to have a good velocity. The twist I've got down to 10 or 12 depending on the bullet and planning to use a 28" barrel. I like to shoot targets also so I figure that is the advantage of the BR. Most shots at varmints are under 500yds but there is always chances for longer shots. I appreciate any comments that you can provide along with any good velocity/accurate loads you've had success with.
