I guess is should be a little more specific, will a 75 action fit into a stock for a 591? Is the spacing between the action bolts the same? and will the 75 have the same round recoil lug on the bottom on the frt bolt hole that the 591 has? I have been looking for another 591 action, but nobody seems to have one to sell, but there seems to be a small number of 75's around here for sale, I want to open up the bolt face to build a SA Mag. if it's possible.
Thanks
