Ok, So besides the Savage I'm considering the Stainless Marlin x7 of New Haven & Black Receivers, Also the later X7 Made in Kentucky? & the 783 Rem Long actions. The purpose is to use Savage Barrels. G states the 783 has the Strongest Action of them All due to the 783 having less unnecessary machining like X7 that weakens the Action. There might be a chance some 783's & X7's have shallower or deeper threads than other compared to the Savages, as I'm told by someone else they won't mount the Savage Barrels.
