As a former Gunsmith of 30 Years, here are some "idea's" and "things" to look for,..
1) Wood Stock ?? I'd, Glass Bed the Action, Recoil Lug, and "Free Float" the barrel ( Glass, the bbl channel, too, to avoid, Forend, "warping" ). I would cut "grooves" in bottom of, the inside of the bbl channel, shaped like a pyramid (with, small, drilled holes at the base of, pyramid) full of glass bed compound bbl sets at TOP of, "Pyramid" with, Tape around bbl to get the desired "gap" around, bbl. Be sure, to PRESS Glass compound into, small holes ( so NO, "bubbles" ).
2) Steel Rings ?? I used ONLY, Redfield or Leupold STEEL,..one or, two piece, Bases with ADJUSTABLE, "Windage" screws, DEGREASED and Loctited down and be SURE to check Base Screw LENGTH, so NOT "bottoming OUT" (hitting threads on Bbl ) that causes a loose Base and,.. SHIFTING, POI !
3) Buy a Leupold, Burris, Vortex or, Sworovski,.. Scope ,..I've NEVER liked, Bushnell,( sorry). I put a 4.5 x 14 X, Burris, on my 7mm Mag. with, turret caps set up, to "Dial",.. to 725 Yards.
4) Make sure all Action Bolts are tight,.. BEFORE start of, season. ( Degrease and Loctite them, usually ONCE and,.. DONE ! )
5) clean and Oil Bbl after, Hunt season then, run dry patch before, zeroing next year and shoot a few "Cold Bore" shots ( 2- 3) after, FINAL, sight in. Remember the Gun bbl. will be COLD when, Hunting ! Find, a GOOD, Gunsmith if you are NOT familiar or uncomfortable doing this "work", yourself ! I've owned 3 Left Handed, Mk5 Wby's and did the above, to all and this, "WORKS" !
