Just a slightly different perspective ....
now that you have your SOCOM 16 all set up the way you like it,
I'll throw you a curve ball ...
Back when I used to compete in three gun [ actually 4 gun cause we always included a revolver friendly stage and encouraged revolvers ] I shot the rifle stage with an 18.5" barreled GENUINE AR 10. I wasn't the best rifle handler around, but I usually won the rifle stages because my rifle was optimised for that particular game. For fast handling MAJOR caliber fast / close CQB type shooting, I have never found anything as good as a short barreled AR 10.
A properly modifed
shortified M14, with a pistol grip and a straight line stock and a good comp can come close, but believe it or not, I found the stock and the pistol grip had more beneficial effect on fast close shooting than did any comp. So all my M14 shorties, and my new M14 alloy EBR stock end up looking a lot like .... you guessed it ... an AR 10.
In addition to the excellent ergonomics pioneered by the AR 10, the OLD ORIGINAL GENUINE AR 10 had a bigger diameter bolt carrier at the back than do the newer AR 10s, which use an AR 15 diameter buffer tube, and make the back of these bolt carriers smaller, to fit inside the AR 15 tube. The original AR 10, with that heavy
bolt carrier reciprocating back and forth at each shot, had very low recoil and very little muzzle rise. The lack of muzzle rise came from the STRAIGHT LINE stock and, as I found with the M14 when properly modified, from the pistol grip acting as a recoil absorber and enhanced recoil control point. But that heavy bolt was also an effective muzzle flip control device, as the heavy bolt coming forward seemed to be timed perfectly to help push the muzzle down just in time for the next quick shot. This was especially noticeable on R&R, when firing the AR 10 and the M14 side by side in full auto.
If you have ever fired a long recoil Browning Auto five shotgun, then you will understand exactly what I am describing here ... the long smoooooth "shuck .. Shuck .. of the heavy action reciprocating along with the shot seems to smooth out the recoil significantly.
So what I am suggesting to you, is that before you get too committed to your SOCOM, that you try an AR 10 for some CQB practice and see how it feels for you
One other serendipitous side effect of choosing an AR 10 over an M14, is that ammo versatility is tremendously increased with an AR 10. I've shot 55 gr Remington accelerators with sabot encased .223 bullets from an AR 10 and an M14, with recoil being near zero with both rifles. So that establishes the bottom end of the usable power scale. This obsolete/ discontinued Rem accelerator ammo was equivalent to a .22- 250 in ballistics, and was incredibly accurate in both my 14s and 10s, and a few bolt actions .308s I tried it in.
I've also shot 110 gr and 125 Gr FACTORY loaded Win .308 ammo in the AR 10, and my current Rem R25 version shoots SUB-moa with some of these hard to find loads.
Next up was my CQB Match
load ... Lapua 124 Gr FMJ .311" bulk buy bullets intended for the 7.62X39 Russian, but loaded into .308 Win cases, with light loads of Win 748 powder giving about 2450 fps. These loads gave minimal recoil, and were accurate enough at closer ranges [ moa @ 100 but not as good after that ].
The usual 7.62 NATO spec BALL ammo was always reliable in both the 14s and the 10s and the Hirternberger NATO spec 7.62 BALL ammo was unusually accurate as well.
Then there were the various 168 Gr HPBT MATCH loads. Each rifle was different, and would have it's individual favorites, but ON AVERAGE, most 14s liked best the Winchester Ranger POLICE USE ONLY version of this weight. I can't get any more of this ammo, but I have a few rounds of the modern Win 168 gr SUPREME Match loads to try next range session. Fed 168 Gr GMM was always a close second, and sometimes the first choice for some 14s.
I could occasionally come close to MOA with some of my 14s, with the ammo they liked best
As for the AR10s, on average they didn't care, and most would reliably shoot SUB-moa with almost any good ammo you fed it.
Once you get past 168 GR bullets, unless you are reducing the velocities, you have left the point where the M14 can be pushed ... reliably!!! But the AR 10 is just getting started. I have shot SUB-moa with my current AR 10/Rem R25, with both 180 gr and 200 gr Soft Point hunting type ammo. No worries about the bolks or receivers or op rods self -destructing because the AR 10 uses a completely different gas system.
So there you have it ...
55 gr to 200 gr bullets, all VERY accurate, out of one rifle ...
and that rifle is the fastest handling BATTLE RIFLE EVER ...
THE AR 10.
I have never hunted BIG pigs ... although I have seen what their trail through the swamp looks like, and that is impressive. I have however hunted moose and Black bear in Northern Canada with an AR 10, and Grizzly with a .308 Rem 600. If I was ever hunting DANGEROUS game again with a .308 Win rifle, I would be looking at 180 gr or 200 gr SP .308 Win ammo to maximise my self confidence.
Can't shoot that heavy a load, reliably, with no M14 that I know of,
