I better go ahead and apologize first, because everything I say from here will be considered stupid.
1.) Full custom or cloned factory, to me, is kind of like going to the prom with the head cheerleader. You can show up in a Lincoln Town car or a Toyota. Once the car is parked it doesn't matter, it's about how well you dance.
2.) As a shooter, I'm average at best. I know some very good shooters. It's the human factor that makes them good shooters. They do their part right, custom or clone. I personally believe that a full custom or a clone that is tuned properly will be more accurate than any person shooting them. So, re-enter the human factor.
This has been a very interesting thread and a topic that will be considered long after we are too old to see through a scope. In all honesty, I'd LOVE to have a full blown custom rig. Would I shoot better? Probably not, but I'd be happier. I value quality, I'm an engineer. I do have to live within my means. If one could point a custom and a clone at the exact same spot without any human interaction, I'd predict that we would see two very very tight groups. Maybe even discernable. Now if we inject the human factor and do the same, I'm sure we'd still see two very good groups, but not as tight as the purely mechanically shot groups. Let us not forget that many times we deal with becoming more precise/accurate by tweaking mechanical things instead of tweaking ourselves.
I'm done.....sorry.
