Practical use of battle rifles

[scipioafricanus]

5.56 works simply for fire time on target. Most of the time baddie only shows himself for a fraction on time. If you try that with a 308 and miss (sight picture, BANG, reacquire sight picture after recoil, baddie gone). 5.56 is easier to walk in your target (sight picture, bang bang bang, baddie down before he is gone).

Now if you wanna chew through a wall, 308 all day.

Honestly 300blk renders PCCs/SMGs obsolete for the most part.

Body armor renders them useless, but it does that to 300blk too (and 7.62x39 beyond close quarters range). That is what brought out the 5.7 FN and similar PDW rounds.

My completely unqualified flight deck squid opinion...

If upgrading 5.56 platform to a 6.5 is off the table then probably stick with 5.56 for reasons stated about (covering fire, qty of rounds carried etc).
Get more convenient personal explosives capability and indirect fire capability into the hands of the average grunts. Why shoot them when you can blow them up from cover?

I remember Vanderboegh doing a post on Mosin M38s and rifle grenades (basically fit out your militia members who aren't sharpshooters as "M38 grenadiers").

[Langenator]

Mosins would require an adapter to launch grenades. Any AR with an A2 birdcage can launch NATO standard grenades (as can FALs, G3s, etc, with STANAG muzzle devices)

Right, but apparently the adapters aren't hard to do. Vanderboegh wrote his post when M38s were south of $100 -- I think that was part of the calculus.
