Thank you, please share actual shots of the targets of prefits in those stocks agging in the .2s in benchrest match. The pictures would be conversational pieces for the old farts (I am 70, and the youngest of the regulars) at our club. They have factory rifles who think they can make them shoot like a bench gun.
Well, the F-class (benchrest on the ground) and the benchrest guys not fighting over the stocks is not a mystery to me. The two disciplines are the front runner in the ultimate precision, the latter drove, pushed the envelope in precision. Not talking accuracy.
Whoever markets those stocks should consider getting a prefit and go out there and kick some butts in benchrest matches, then maybe he would get some following from that crowd. The Super Shoot would be great venue, or the upcoming TX Long Range Championship, where some the best F Class guys would be shooting. There is nothing more convincing than the old adage... "show me"
Here is my take universal fit. My brother's VFS gun is based on a glued custom action built by the action manufacturer. When he was ready to re-barrel he asked me to do it, that was about 6 years ago. I did not want to see his rifle till I was ready to screw the barrel in. He provided me the tenon print from the manufacturer. I cut the new barrel exactly to the print. He came over, I unchucked the barrel, unscrewed the old barrel. Remember this a glued action (very common practice within the stool shooting crowd), the dang barrel I did would not screw in. Verified the tenon to the print, all was well. So I called the retired benchrest smith who mentored me in chambering. He suggested instead of relying to the published tenon print just measure the old barrel tenon since it was chambered by the action manufacturer. Well, long story short the published tenon print might be right, but the action could be off spec. Bottom line the actual pitch diameter on the barrel is much smaller than the published print. Then, I had to rechuck the barrel, indicate it again at 2 places, and chased the thread... what a pain. Can't test fit a glued action.
Moral of the story -- varying manufacturing tolerances may negate the universality of application.
