Well in .308 especially my .308 Montanas a 1:12 which limits me to 180s and less if I wanted play with longer skinnier bullets. Couple that with a mag box to actually allow you to run long bullets and actually seat to the lands...it just gives you more options.
Don't get me wrong I like my Kimbers and will def keep atleast 2 of the 4 I have as the fieldcrafts fill the niche they do (358 win and 338-06) but the current 308 win and the incoming 6.5 mountain ascent may be down the road so if anyone is interest.
