I'd like to know if the newer 300 wsm actions are large or small shank, and whether the screw spacing is 4.4", and whether a model 16 300 wsm barreled action with dbm and bottom metal could be swapped directly into a chassis/stock inletted for short action dbm. Of all the possible ways to build a 300 wsm, buying an action already set up for it and slapping it into a new stock with rebarrel seems the least labor intensive. Thanks in advance.
