Ill jump in since it seems more Americans have Canadian views than
Canadians.
Those cartridges exist to fit in the space constraints of the AR platform.
Unless you have one of a very few actions scaled to fit them,
what's the point?
I can load 6x45 or Grendel performance from 6mm/243 or 260/Creed
if I want that low performance from a short action.
Given the recoil levels of full power loads, I can't imagine a reason to.
If I'm trying to suit a kid, lower pressured rounds would help noise levels
slightly. Advantage bigger rounds.
223 I can see due to high volume varmints. Thats not me though.
Not if CZ would change their safety and price the guns like they were
in the past? A Grende l or a 7.62x39 would be cool as hell in a tiny
527 Carbine.
JMHO
