Re: 308 ftr
I only ever got to play with one of these and it shot great consistantly in the 1/2" range with several handloads.
Eddybo is right , I've never seen a 308 that woulden't shoot at least reasonably well with a 168gr bullet over 45grs of Varget , thats a mid range load and leave plenty of room to play with powder charge and seating depth.
If it diden't shoot factory match ammo under an inch that their is likely a problem , either the action is moving in the stock due to no bedded or improperly tight action screws or somthing as easy as a little ding on the crown , heck the crown may not be cut strait.
As for the powders , N-140 , N-540 and N-550 all from Vihta Vuori are all in the range your looking for with the 155-175gr pills. Varget and H-4895 are also very good powders to use the the 308
