I worked up a load for my son's B-I-L, a new 6.5-284 with accufit stock. First thing I do is pull the stock, factory finger tight....any pillared stock IMHO should be at least 30 in/lbs..put it back to 45 front, 35 rear...1/2" groups right away before developement..
With most pillared stocks those torqued should maintain. The plastic Tupperware stocks are more suseptable to loosening because they bend between the screws at recoil.
