All of my fondest memories involve a Model 70. Mostly because of my dad, him being the 1-gun Model 70 guy.
If it ever comes down to one and only one, I'd probably start with a stainless Model 70 action, thread on a nice 22" fluted medium contour barrel with an 11 degree crown, chambered in boring old .30-06, a Timney trigger set at 1.5 pounds, and both a high gloss, high grade walnut stock and a McMillan Game Scout in the off chance I'll get to hunt the far side of the Rockies.
I really like the aesthetic of the Remington 700 CDL SF, but I want it on a Model 70 action.
