I knew a fellow that had a wildcat 243/06 in a big heavy bolt gun. He wanted the same cartridge in a lighter handier gun so he bought a Ruger #1 in 25/06 with plans to rebarrel it. He took it to the range to shoot it some and liked the accuracy of it so much he left it a .25 cal. and still hunts with it to this day. I believe his son bought one in .270 win. awhile after his dad started using the 25/06.
