In the end, the 6.8 SPC will be where the AR system evolves into. IMHO. It is an excellent cartridge, requiring only a bolt and magazine change to function in the AR system and awesome downrange ballistics.
Now if they had necked down the M1 Carbine to 6.5 in the begining we wouldn't be having these issues.
Pardon my ignorance, but what was the M1 Carbine necked down to 6.5 capable of? That’s a new one by me. Never heard of it before.
The last “new thing” I saw with the M1 Carbine round was a pistol chambered in M1 Carbine. One *heck* of a muzzle flash on an indoor range. Woof. Other than that, nothing terribly notable.
I used to have a M1 Carbine. Traded it in on a .17 HMR. The .17 HMR is a squirrel killing machine for this (now ex) farmer. There’s been nothing quite so well suited for the application (farmer killing rodents) as the .17 HMR. It has completely taken over from the .22LR rifles the job of killing ground squirrels on hay farms in Nevada in a few short years. The .17 HMR was the first product where I felt moved to write a “thank you” letter to the CEO of the company that created it, ie, Hornady. Wonderful product for what it does (kill squirrels and jackrabbits), IMO.
Love my .17 HMR, as you can tell.
The M1 Carbine? Never used the thing. Never was that accurate. Wondered why we (the US) ever made the thing. What as the point again? To replace a pistol? For me, a 1911 in .45 ACP always seemed to dispatch coyotes better than a M1 Carbine.
