Comparing a Rem 700 action to an action made by someone like Stiller, Defiance etc... Is there a huge difference in precision shooting, maintenance, rigidity etc..? I want to build a custom rifle from the ground up and being a lefty it's pretty much what I have to do in order to get exactly what I want. I now there's differences in barrels and stocks but does a custom action completely outshine an off the shelf Remmy or even a Savage? Stiller has an amazing group buy for $750+ on an action. But I can also buy a Rem 700 Varmint for about $770 then sell the stock and barrel and come out paying about $500. Don't get me wrong, I'd rather have the Stiller but if there really isn't a difference then is it just moreso the look and finish of a custom action?
