Yes but
and then the 5.56 showed up. What happened then?
That would be the cartridge, not the action. The entire short action thing is overrated (totally in hunting guns).
Do you think a 308 sporter type rifle on a short action would shoot noticeably different than a 308 on a long action?
in anything less than a benchrest rifle, there's no measurable difference (and even then...). You don't need multiple length actions. Tikka/Sako is doing an excellent job of proving this.
I am a big fan of the 6.5x55. It goes on a moderate/long action. It has just as much a distinguished target shooting history as the 308 (it's been around quite a while longer).
BTW. People build NM target rifles on the Tikka actions. Savage, not so much.
You guys are forgetting to mention arguably the neatest thing about the Savage, The barrel nut. The ease with which you can swap barrels/calibers and set headspacing.
