I have the chance of a cheap rem 700 as a donor rifle for conversion from 22-250 into something useful. Does anyone know if the standard .308 action length is ok for a .30 cal in a 55mm case? I'm not looking to buy something decent, just a test bed so dont bother trying to sway me I just want info on action length. Edited to add that the bullet will be a standard 150 grain (at the mo) Sierra game king type! I'm more for accuraccy testing and feeding from the mag to make the testing easier!
