You will just have to see what your rifle likes, one ofmy buddies 700CDL that was just slightly accurised, bedded the action and floated the barrel channel, loves 100gr of Retumbo pushing a 180gr TSX, it will group .5 off a Lead Sled. Another buddies 700 that was fully accurized and rebarreled shoots better with BMG, besides, experimenting is half the fun!.
