I dont think that the 8mm mauser would not fit in a short action(3.25 overall length),the 308 is 2.80 and the 358 is 2.78.I am not really a bean counter but I think that this might work.Using H380 as a good reference,the8mm mauser uses 42gr.of powder to push a 220 gr hornady 2107fps. the 308 uses 45gr.in a compressed load to move a 200 gr.bullet 2440fps.the 358 win burns 54 gr.to get a 200gr.sp to 2375fps also a compressed load.(Lyman book).Is 2500 fps possible from this round in the Ackley version with the 225 gr hornady,or am I pissing in the wind?
