Agreed. I probably got side-tracked by the Creed and "poor man's .270" comment...but there are so many suggestions being thrown around here when people don't even know why the OP wants to change.

He said he wanted to turn his rifle into a 7mm Rem Mag...which would require a rebarrel...which he doesn't want to do.

Someone suggested a rechamber to the .270Wby and the OP seemed giddy at the thought.

That tells me that the OP just wants an increase in horsepower. Why? Who knows...he didn't say...but if he wants an increase in HP, why suggest assorted chamberings that require a different barrel when that is the ONE thing we know the OP doesn't want?
