Well KN, my opinion which is based totally on unscientific data is that a gun will not always shoot the best with the bullet barely off the rifling as is the generally accepted rule. I think a lot of guns are like this, but others like yours might like a little more space. I always think about my Contender barrels in 357 Max, 41 Mag and 44 Mag. They all have a big forcing cone and their is no way you could seat the bullets to almost touch the rifling yet these barrels will shoot 5 shot 50 yard groups with the holes touching. Would seating the bullet to touch the rifling make a difference (if you could)? It might, but you would never know because you would not know if your 2nd-5th shot went through the first hole or missed the target all together (little bit of humor there).
I also think of factory ammo. Some factory ammo will turn in impressive groups with factory rifles. These bullets are a long ways from the rifling.
Bottom line for me, barely touching might help, might not help. I just seat to the COL in the reloading manual unless I cannot make the gun shoot to satisfy me, then begin to play with COL. But I never just assume that seating the bullet .030 off the rifling is the answer to the accuacy prayers.
