I have a Howa 1500 in .338 that gave me fits for some time. I replaced the Tupperware stock with a laminated Boyds JRS, then played with various bedding options before arriving at a full-bedded solution. What REALLY made the difference in this rifle, however, was the discovery that it truly preferred near max loads. Groups shrank from 2.5" to <1" when I got within a grain or two of max. (I'd been trying to work up .338-'06 level loads). Subsequent discussions with knowledgable folks have reinforced my discovery. Apparently, my experience isn't at all unique.
But when it's all done and perking properly...how sweet it is!
