This is a CBI with a 0.093" freebore. 87vmax and 105s are about a perfect fit for this from what I've seen so far. Is there anything lighter out there for varmints? 55 Nosler BTs isnt in the case at all to touch the lands. 70tnts have about 0.155" in the case neck when touching the lands. Can some of the light bullets handle 0.100" jumps and shoot well from a 8t barrel? Thanks!
