Please help if you can. Over the past year or so, I have noticed that my Model 66-2 is slowly losing accuracy. Having a cloverleaf size group at 25 yards was not uncommon. Now, I am lucky if I can get 2 inches in the same condition. I know 2 inches isn't bad but this gun used to shoot better. This gun has MANY rounds through it (I don't keep accuarte records of that sort of thing but I would guess well over 10K). Most of those rounds have been very light 38 special loads with lead 150-160 grain bullets. The load hasn't changed. I haven't changed (bench rest and other guns prove that in this situation). The gun seems just as tight as my other model 66 example (that shoots much better). I am now wondering about the forcing cone. I doesn't look worn out but is that the best way to check it? Does anyone make a guage of some sort? What angle does S&W use? Is it the same for all models? Has anyone had success with Brownells forcing cone tool?
I am thinking this barrel may need to be turned in a turn but I am was hoping someone here could shed some light with personal experience.
Thanks for the help,
Mark
