I have been waiting on the parts to do my first barrel swap. Got a Axis last week in 243 with accutrigger and decided to take the plunge. Had picked up the tools I needed ( barrel vise, nut wrench and go/no go gauges ) and a few barrels over the last couple of months. The 243 barrel was a little hard to get off as I expected, went slow so not to mess up threads and cleaned all parts real well. Threaded nut on replacement barrel (270 ) and threaded it on action to be sure all worked ok, checked head space several times as things moved as I went to lock barrel down. After I was sure things were ok locked barrel down, took out of vise and checked head space a couple more times to be sure. Put in a stock I had roctited and painted added scope and all left to do is go shoot. Kinda nervous on first change but not hard to do. Will post after I shoot as to how it all worked together.
