I could, but easier to neck down the 300WSM brass - neck is already big enough to create the false shoulder. Would have to expand the 270WSM brass necks, then partially size it back down to create the false shoulder.
On another note, started prepping the stock for bedding last night, finshed up tonight - taped off the recoil lug and the stock where it was needed, removed the trigger and filled the opening with modeling clay, several layers of tape around the barrel to center it/keep the same gap all around, enough tape around "bedding bolts" give the screws plenty of clearance after bedding, sprayed the bbl'd action with One Shot liberally, etc. Mixed up the MarineTex and got it bedded!
Think it's ready to hit the range Saturday! Wind shows to be 2-5mph in the am, so should be a good day to test the accuracy.
