after 6 weeks of hard hunting in alot of nasty weather ,4 deer in the freezer i brought in triumph for a good cleaning.i found pitting in the barrel above the breech about 3" till 4"short of the muzzle.i always cleaned between shots using 2 wet patches of#13cleaner,2dry,then a patch of T17 lube.so i scubbed bore with a brass brush and took it out to the range.grouping may have opened a little or it may have been me but it was still shooting great,now i have put apx. 250 rnds thru this triumph shooting 130g 2f 777 with either maxiballs or 250g sst/sw.I"m now noticeing that it does"nt lock up as tight as it used to.ship it out to t/c with anote to tightin up the action and to please inspect the barrel and see if i can buy another barrel for my favorite ML.T/C sends me back a brand new triumph!!!I"m feeling happy and guilty at the same time.whut a great company! karl
