hey rev...first off...the mans words were...Why "Wrong" Jink? I was kinda thinking that I might look into an Armalite AR10 in .308. So I would be interested in hearing why you believe 5.56 is superior to 7.62X51/.308. Other than the ability to carry more 5.56 for a given weight, and 5.56 costing less, I am not aware of any ballistic or functional benefit to 5.56 VS 7.62X51.wrong.I have an M4 style Bushmaster and its a good weapon - actually its the wife's gun.
Its been dependable and is cheap to shoot and carry. I have used it on the job to keep evil spirits away and it works ok for that too.
The Springfield variant you have posted is a good idea, they are pricey but are a FAR better, shot for shot weapon than any black rifle - anything a .223 will do a .308 will do better!
The SEALS live and die by the M1A1 and it's 7.62 round. Out to 1000 yards or so it's functional, and it hits much harder than 5.56 in close. There are also elements at SOCOM that swear by 7.62 and the M1A1s ability to reach out and touch someone/something.
So I am curious. The 5.56 was developed for a close range environment, I.E. Jungle, Out to about 300 yrds or so, it's a compromise between Firepower and Stopping power, as are the other assault rifle calibers.
Or Something like that.... I read something somewhere....
"anything a .223 will do a .308 will do better"
and that's what's "wrong"...as it's simply not true.
and not to brag but just to quantify my words my background includes Marine Corps Rifle Expert (High Shooter Of My Platoon)...offered Sniper and then P.M.I. coming out of boot..I refused both...also?..I've competed in several hundred organized tactical competitions..with about a hundred of those tactical challenge events being "3 Gun Competitions" (including pistol, rifle and shotgun)...all were timed events with shots fired from several stations and positions with "on-the-run reloading"...and it was during these events I saw the first hand weaknesses and strengths of many popular combat rifle variants...and just about all were customized "Race Guns".
The .308/M1A: was drastically out of it's element...and at tactical distances of less than 100 yards it's power becomes it's weakness...with full power loads and no recoil buffering system leaving the operator posting shot-too-shot recovery times double that of the much faster handling AR variants.
Other tactical downsides include: Low 20 rd mag capacity and a very slow and clumsy "rock-it-out/rock-it-in" mag changing system..also?...I can pack 600rds of .223 as easily as just 200rds of .308 as not only are the .308 rounds 3x's the cost but also 3x's the "WEIGHT".
That said?..I love the old M-14 full battle rifles and once owned a Springfield N.M. M1A with a Gen.II scope...and at ranges of 200-500 yards?..it was so accurate it was boring. LOL!..but again..that's a full sized service rifle...and that's where the .308 shines...as a mid-range sniper rifle...however..these bastardized 16"er socoms are somewhat of a joke to me...as they've taken the mighty 7.62 and the short 16" barrels have neutered it down to 7.62X39 velocities and power factors..and for what?..just to romance the old ergonomically incorrect M-14?..that's just foolishness imho.
The AK Variants: Used them and loved them as well but...while reliable as the newspaper boy?...even the best examples suffer lackluster accuracy and sport even worse ergo's than the M1A as your hand hasta leave the grip position just to activate the safety and requires "two-handed-mag-changes"...which sux when you're in a timed and stressful situation as it rarely goes smoothly.
The AR: is everything a mid-sized battle rifle should be...light...fast handling annnd.."ergo correct" to the extreme...as your grip hand never has to leave position to either operate the safety oorrrrrr...execute a speedy mag change...and while it doesn't sport the knockdown power of the .308?...it more than makes up for it by way of accuracy and speed....and the .223 round has come a long ways in the past decade..including winchesters "Q" loads which are "Frangible FMJ's"..they don't zip in and zip out...or "tumble"...they simple hit...penetrate...and then "grenade"....dumping the ful load of energy into it's hamburgered victim...no lack of effect there.
I like'em all...but I love the AR's for their fast handling speed, accuracy, versatlity, ammo cost, capacity and all associated lightweight gear and ammo.
Here's a Bushy Flat-Top BAR-10 that I put together about 2 years back...and then sold about a year ago..it was my "SNIPETAC" project rifle...it wore a 4-16X Nikon Mil-Dot Tactical set in I.O.R. Valdada H.D. Ringsets with a Harris Bi-pod modified to "lockpivot"...
The idea?...as the name "SnipeTac" infers?...it was supposed to be a cross between a mid-range snipe and tacical rifle...and it failed...as it did both okay but neither one well...ego correct but...still heavy...still slow...and at engagments of less than 200yds?...I'd be suxing hind #####...and toting low count, high cost and weight...rounds.
so does the .308 do everything better?...not in this lifetime.
