I have been thinking of building a 7mm TCU on a savage action, but I have a couple of questions before I bite the bullet and start this build. Has anyone here built one of these on a savage action? What action should I use? I want a repeater but I don't think the cartridge will fit in the mag on a .223 action, maybe a 22/250 action with .223 bolt head and some mag tweaking. Any advice is appreciated, and I know i could probably do a ton of other cartridges, but I just want a 7mm TCU. Thanks Kris
