I might be late to the party, but I'd caution against porting the barrel on a hunting gun. Going from the quiet of the tree stand to the deafening crash of firing it will not be fun. I've shot my stock .30-06 and a friend's that was ported back to back and the recoil reduction was nowhere near worthwhile to me. Good luck with the .25-06 though, I've heard a lot of good about the caliber.
