Thanks, but already done it to the factory stock (see the OP). As thin as I dare. This rifle's been in my hand every year since '81/'82 (getting old, can't remember), and its going nowhere. So I had no reservation about doing as I pleased. It came out well (and I'm considering having it re-checkered), just not as thin as I'd like.
Looking hard at a Browning X-bolt now. SR model with a 18" barrel. Checks most all of my boxes: bolt-locking tang-safety, out-of-box accuracy, DBM (albeit 4 rnds, rather have 5 ala Sako & Mauser), decent trigger (better than an M77, anyway) modern stock geometry, open loading port area (really open with one piece base/rings), 6.3#, threaded. Pretty much what I was trying to achieve when I bobbed the barrel on the 308 M77 TS I have, except that gun is only slightly lighter than the full length rifle, and just as thick.
