I have been reading from this website for the last few months and have become more and more interested in having a LR gun made. My biggest problem right now is the financing to do so. From what I've been reading, it appears that most gunsmiths prefer building on Remington 700 actions as far as building up from a store built factory gun. So my question is, in planning for a future LR gun, would I be wise to look for a Remington 700 base model that in a few years could have so work done too? Or wait and try and get a custom action. Also is there a difference in actions between different grades of Rem. 700? One last question, how close in caliber does a existing rife have to be in order to build a LR gun out of it? (example do you have to use a .338 to build a .338AX or 338 Edge?) Thanks for any advice in advance.
