I really like the way the 16" barrels "feel" on my ARs and am contemplating selling a NIB BM with a 20" barrel and sticking with all 16s. Most of my hunting/shooting is under 300 yards with only plinking/gong-work beyond that (at least so far). What will I be giving up with a 16" vs. 20" barrel for a 223 Rem??

I'm also planning on picking up a 16" AR10 soon so any input on 308 Win performance with 16"/20" barrels would also be appreciated.

Thanks for your input.

www.ammo-oracle.com--when in doubt check the oracle

h/w, i dont remember if it had any ballistic/velcoity/energy charts.....

you will be giving up velocity and more than likely frag range

Remington's ammo ballistic charts specify the given velocities as valid out of a 24" barrel, and state that one should estimate about 50 fps lost for every 2" of barrel as a rule of thumb.

Great link. So what happens to bad guys/varmints hit beyond the frag-limits??? Giggle and walk away or just a slower death by smaller hole???

Depends on where they are hit. But even if the slug doesn't fragment, it still yaws, like nearly all other slugs. But the damage is alot less than if it fragmented. That .224 hole will still bleed, still damage stuff, but it may not be enough for an immediate stop. Especially against Muslim insurgents all hopped up on drugs.

That's why I don't understand why the Army is using M855 and M4s. M4 and M193 would be a better combintion; longer effective fragmentation range.

Your January American Rifleman has a test of the Socom II 16" M1A. Check out the velocity specs and energy there. Pretty surprising.

The only thing is with the springfield rifles coming out now is that chrome lined barrels are no longer offered.I emailed them and they confirmed that for me.

Sometimes that extra velocity might be preferrable...ie in conditions that would warrant some extra velocity and / or penetration.

I know in Maine, medium to large sized game either wears a thick coat of fur, or an insulated parka.

I think it's atrocious for a Mainer to NOT have at least ONE 20" AR in the arsenal.
