[VASCAR2]

Stan have you seen the new IMI armor piercing ammo? Doesn’t give much information.

Why not keep improved 5.56 for magazine fed weapons? It seems most problems with it have been fixed. Like LRRP52 I think machine guns are the major problem. What about a light, constant recoil machine gun using 140 gr steel and aluminum long bullets? Combined with light cases and fairly high speeds ,how would it perform?

It sure doesn't. When I saw that IMI publicity sheet a few months ago, I searched for more info, but found nothing.

I agree.

Beats me. The only thing close that comes to mind are the long, aluminum-core projectiles developed at CETME around 60 years ago, but I've never seen any performance info.

I tried to calculate the bc of a 30 cal 140 grain bullet with the form factor of the 200 gr match king. but my algebra has left me.

Looks like the Army is going with 6.8mm for its Next Gen Squad Weapons: https://www.thefirearmblog.com/blog/2018...d-weapons/
