[QUOTE="hemiford, post: 908317, member: 72104"] OK. Some of my questions have been addressed. Very good instructional videos. Some of the factory machining is undeniably improved. Now I have another question. If a factory built rifle shoots one MOA using GOOD bullets, all the stacked up out-of-whack tolerances still produce a certain repeatability. Isn't the repeatability, the one MOA groups, the name of the game ? If you take the same action and blueprint it and put the same barrel back on it (assume here that the barrel threads were OK just for this example), won't it still shoot the same groups ? If you change the equation by installing a better (longer, heavier, etc.) barrel, then using the SAME bullets I would expect better repeatability, i.e., smaller groups. If you perform a good pillar bedding, you could expect possibly even better grouping. I still have a couple of concerns, and I think what I am getting at here is, other things besides the action truing will produce better overall rifle accuracy. Maybe I'm incorrect to think this. I'm also not happy about requiring non-standard/oversize threads on any future barrel for the gun. [/QUOTE]
