My 308 Izzy is telling me it would like to run some 30-06, so I remove the spacers in the feedway, change the booster orifice and pop in a 30-06 barrel is that it ? So the 06 barrels are a little more scarce than the 308 ones, is there any reason not to take a 308 barrel and run a 06 chamber reamer in it ? ( not my first chamber), ? I’ll want to get a barrel blueprint before I do it, but it seems like the most economical way for me to go to 06, everyone has 308 barrels in various states of condition fairly reasonable priced. Thanks guys for all your comments and thoughts, Jon P.
