...subsonic 45-70.

Why do that when you can do this?



45 Colt mo better

This seems like a very rational approach.

If one needed big slow pills from an AR, isn't that what 458 SOCOM is for?

I think that .458 is ballistically more efficient than other .45 options listed so far.

Sure, compared to an AR that can take pointed bullets, the .45 Colt is not the best choice. But if you are considering subsonic .45-70, the Colt can do that out of a much smaller and lighter rifle. Yeah, you give up some of the bullet weight that's possible, but 300+ grains out of a light and handy carbine with greater mag capacity is nothing to sneeze at.

Also doesn’t hurt that the action design lends itself to the same sort of muffling as a bolt-action, while the AR platform will make more noise with the can. Once again, an application of the power of “and” here solves most issues.

I just started reading that cause heaviest bullets I could think of off the top of my head and when I started looking I was surprised at how much discussion I found, plus there was commercially available ammo apparently meant to be subsonic with max bullet weight. (Edit to add, like 550 gr)
