[QUOTE="Idaho Lefty, post: 2199961, member: 104437"] @ Weaselthis,.. I got, "Tip TOP" 1/2 MOA, accuracy out of, my 2 Tikka T-3's, one in .270 WSM the other a .243 Win by,.. 1) clean, the Barrels with Barnes C-10, to remove existing, copper / fouling. 2) Put a lightly oiled, cotton Patch over, a Bronze Brush "slathered" with, JB's and run this tight fitting, combo, thru your barrel ONE WAY 12-15 strokes ( unscrewing Brush after each pass ). *** Do about, 5-6 Extra "passes" in out of, the THROAT "area" only, do THIS, FIRST ( Smoothes the Reamer marks from, factory Chambering ). Finish with, the 12-15 passes, ONE Way. Changing Patches, add fresh JB's, a couple of times. 3) Clean barrel and Chamber,.. THOROUGHLY ! Lightly Oil and DRY Barrel and chamber ! 4 ) Shoot 5 rounds SLOWLY, Clean, shoot 5 more, Clean again, Barrel should look like Chrome and NOT, "hold" very much Copper, afterward. My .243 Win Tikka has shot, 1/3", 5 shot groups with, 87 HVLD Berger's and the .270 WSM gets sub 1/2" to 5/8" MOA groups. The reason your Rifle is showing Copper Fouling is that, the Chamber / throat have been, freshly cut and edges are, Sharp ! I have used, THIS "Method" on 2 Tikka Barrels, A New, 6xc Criterion Barrel and a Green mountain .22 LR Barrel. [/QUOTE]
