The reason there are more custom actions that are copies of the Rem 700 is because it is a simple and effective design made up of fairly simple and easy-to-copy parts. The receiver is machined from tubing. The recoil lug is stamped out of flat stock. The bolt body is fabricated from three pieces: the handle, body tube, and bolt head.
The Winchester and Ruger receivers must be investment cast, forged or machined from bar stock. The recoil lug is an intregal part of the receiver, and that complicates the manufacturing process. Since there are VERY few, if any, custom gun shops that have the capability of investment casting, that leaves only machining from bar stock or machining from forgings to produce a Win or Ruger receiver. And that takes a lot more time and machining operations than what is required to produce a Rem receiver. And every added machining operation and every added second of time increases the manufacturing cost. In addition, the raw material costs for each of these options is higher than the Rem.
The Ruger and Win bolt bodies are one piece, again requiring either investment casting, forging or machining from bar stock. And for the same reasons as the receiver, it's much more costly to produce a Ruger or Win type of bolt.
Which is better? It's a matter of personal taste. I personally like and appreciate all the extra work and craftsmanship that goes into the Win and Ruger. BUT, if I was in business to produce a custom action, it would be MUCH easier for me to build Rem style ones. I could make Ruger or Win style, but they would cost quite a bit more.
Which design is ultimately more accurate? I would say neither (but that's another debate). You could keep diddling with all three of them and probably reach equal accuracy with all three. But for
maintaining benchrest quality accuracy, through multiple barrel changes, the Rem design is certainly
easier because of the easily replaceable recoil lug that protects the front face of the receiver.
All the upgrades that y'all mentioned doing to out-of-the-box Rem 700's, if done to ANY commercial bolt-action rifle will achieve the same results. So there's sure not anything special about them in that department. And Dave in WV is right: because they are so simple, easy and cheap to manufacture, they ought to cost less than most of the competition, but they don't. That's why I'm not a Rem 700 fan. But you've got to give them credit: they've got a GREAT marketing department. I'm gonna shut up now. Sorry about the long post.
