[...]can yall explain in a little more detail why a remm would require more smith worh and why a savage would not?
I can't do that topic justice. There are folks a lot better qualified to explain the details. ...and, many internet and hardbound publications that go into detail. But, here is my take on it in a nutshell.... So, please don't misconstrue my comments to suggest that you simply unscrew and screw on a new barrel.
Rem 700 is popular for customization because it's made with a relative few simple machining operations resulting in a strong yet affordable action that's easily tunable on a lathe. ...many millions sold and customized over 40+ years.
However, the barrel nut and floating bolt head design of the Savage make it such that a non-gunsmith can actually change out the barrel with good results provided that they follow the proper safety precautions to headspace, etc... Doing the job improperly can be disasterous with any firearm. But with a Savage, it can be done with basic tools to include a set of go/no-go guages.
Whereas the Rem 700 almost certainly will require a lathe to properly install a barrel although some accurazing such as floating the barrel and bedding the action is well within your capabilities. Some claim the Savage Accustock does not require bedding and the Savage accutrigger is designed for adjustment by you. For that matter, you can adjust your 700 trigger also, but whenever messing with triggers/safeties, you need to know and practice some very solid safety precautions.
Nonetheless, there are still many tuning/blueprinting tweaks for both actions that require special knowledge and tools that go beyond the do-it-yourself-er. Trueing and blueprinting may or may not be required to achieve the accuracy you desire.
Win Mod 70 on the other hand is an excellent action. But, it is apparently more complicated and expensive to work on. Many smiths specialize in specific actions and only tool up for the ones they work on. If your smith says he doesn't like Savage, or won't work on Rem, then don't try to compell him.
Hope this helps and perhaps someone can explain better or point you to specific threads and publications.
