Is it me or do I detect a hint of "5.56 bashing" occurring here on a subliminal level. One glaring point I see in all the "5.56 can't do this or that" posts is...mismatching the round with the weapon system for the intended job you want it to do.
Ammo Oracle says that 5.56 needs ~2700 fps to work at peak function,fine then:
1) why issue a CQB 14.5" barrel for long range(300yd+) target encounters. Yes you can hit the target, but terminal velocity has suffered to the point you only make .22 holes instead of desired fragmentation. Its my understanding from other threads that frag. velocity for M4 length bbls begins to drop off after ~150yds,some claim even shorter.
2) since Somoli's,Taliban or other Afgani loyalists don't have easy access to Kevlar helmets or Type III ballistic vests, why are we using M855 ammo when it would appear that M193, with its higher velocity, better fragmentation and similar penetration (thru clothing) would be the better round?
3)an even better round for CQB would be a softpoint; still retain penetration with maximum expansion and fragmentation.
4)20" bbls seem to work best for the 5.56, but the bitchpoint seems to be the weight. Well yeah, luggin' a bullbarrel around would be a problem but a thinner barrel would solve that..jeez look at the mini-14, its an 18.5" bbl so I wouldn't think an extra 1.5" of steel is gonna break anybody's back.
I am no ballistics expert by any stretch of the imagination, in fact, for a long time I thought anything under .30 cal was for girls. That changed after I finally got an AR and started seeing what it could do, and what the different ammo types could do (hp,fmj,V-max,etc) It just seems to me that a lot of .223 bashing comes from mismatching the ammo with the weaponsystem more than anything else. Correcting the mismatch seems to make more sense than having the govt scrap an entire inventory of rifles,if that happens I'll bet it won't be 3months before you start seein' the same gripes show up again.
Please pause while I put on my asbestoes underwear and Nomex coat before you begin the flamin'....Thanks
