'tarnal...... just to give you an idea how much I do care about this question, even after literally 25yrs of getting it answered...... I own a Kensler rail. I've got a Neuvo drop port ordered for it. I've got a Bat dedicated to it at present, and a 721 and an old Savage 340 and a state -of-the-art 700 to run basically head-to-head (altho some are BR's, not PPC's)
My point is, I'm stupid enough and stubborn enough to KEEP ON exploring this question......
But at present I'll stick to my guns. Custom actions are TOO CHEAP!! Just 'WAYY TOO GOOD A VALUE to pass up. Yes, a true craftsman like George Ulrich or Alex or Ryan Pierce who're willing and able, guys who've taken the time to learn WHY actions shoot better and fix them....can make a Rem700 shoot. But this is because the CRAFTSMANSHIP is better, in the end the 700's still not worth the money invested.
And I'll say it again, IT IS THE ARROW. Lotsa' folks prolly got access to an Osage Orange tree.... but ain't but 5 folks on the planet can make a worthy hunting bow out of that tree....
And that some folks like the Kelbly's and Jim Borden long ago decided to make their own stuff instead of fixing others' stuff.
(And I don't mean to start an argument here with George re "fixing custom stuff too!!" Cuz George is RIGHT....)
But IME, the Borden and Kelbly stuff for instance is CHEAPER to make good than Rem700s......in the long run.
