SC, i just restocked my Model 70 270 Win. in a Laminated stock and glass bedded the action and about 2.5 inches of the barrel. The rifle is grouping about like yours. Before, i had it stocked in a glass stock with the barrel completely floated and the rifle grouped the same load just under 3/4 inch's. I believe the problem is bedding the 2.5 inch's of the barrel . I'm going to take out the bedding in the barrel channel and completely float the barrel , i just haven't had time to do the work. I have had this problem before by glassing part of the barrel channel. But if i was you, i would make sure your bedding screws are not to long and touching your bolt and that the pillar hole are large enough so the screws are not binding against the stock if this checks out OK then look at the barrel channel bedding. One more word of advice , you must be careful lapping the lugs because you can change the head space and make it excessive , lapping should be done before the rifle is barrelled and head spaced /ubbthreads/images/graemlins/grinning-smiley-003.gif
