Accurate, Barrier Blind .223/5.56mm?

[DRT]

I love the accuracy of 75gr T2 5.56mm TAP. It regularly shoots 1.25- 1.5MOA in my free-floated 16" and 20" Colt barrels (1:7).

I'm having trouble finding factory barrier blind ammo that provides similar accuracy. The 70gr TSX by SSA is the closest at around 2MOA. The remington 62gr is 3MOA and the 62gr XM223SP1 around 2-2.25MOA. Reports I've read indicate that mk318 accuracy is also mediocre. OK for relatively close range but I'd like to be able to accurately shoot to extended ranges.

I suspect that the 5.56mm TBBC load (currently unobtainium) won't be very accurate since the .223 version was a 2.5-3MOA round. I'm curious about the accuracy of the new 5.56 64gr winchester bonded offering. I'm wondering it is uses a bullet similar to the accubond. If so, then it might be the ticket.

Has anyone else found a good barrier blind round that's accurate out to 300M?

Have you tried any of the lighter weight TSX rounds?

[DRT]

No I have not. Have you any experience and/or seen any reports involving the BH 50gr tsx 5.56mm?

No personal experience, but I remember hearing they were pretty accurate. Whether they are sub 2 moa, I have no idea. This topic was actually something I was thinking about earlier since I'm planning a "semi-precision" recce build.

Btw, are you sure all you're getting is 1.25-1.5" groups with the TAP? I've heard of much better in the accuracy department from them...

I have on a couple of occasions gotten just over an inch at 100 yards out of my 20" rifle, but 1.25-1.5" is much more the norm. These are A2 profile, gov't barrels w/legit 556 chamber, albeit free-floated, so I'm sure a tighter, more precision-oriented barrel (e.g. noveske) would do better. A better shooter behind the trigger might do better too.

By the way, I have the privilege of having property to be able to shoot at 'extended' ranges out to 400M. Judging the wind accurately, particularly with a .224 bullet, is a critical skill that I'm working on. I good laser ranger is helpful for longer ranges too. I'm having a lot of fun shooting steel swinging targets at longer ranges. I love the feedback vs shooting at paper.

Yeah with that barrel, you're getting pretty decent groups.

Now as far as your land....you wouldn't happen to be in TX would you?

[Ironman8]

Another round that I have heard had pretty decent accuracy is the Speer 24448 (.223)...have you tried that one yet?

Aside from rebarreling your rifle, you might not see much better accuracy than you're seeing from the TAP.

The 64 gr speer load is what Im duplicating this fall as soon as I run out of 75gr Hornady OTMs. Im going to work up a load with the 64 gr powerpoint and 65 gr gameking to see which groups tighter with my rifles. Im picking up a couple boxes from GT Distributors this month to compare with the chrono.

USG Mk318 Mod0 has a 2 MOA lot acceptance accuracy requirement; it is quite accurate for a combat cartridge--much more so than many recent lots of M855 which can be up to 6 MOA.

I am curious why you think 2-3 MOA is an issue out of a standard Colt USG chrome lined barrel with non-match grade ammo. 2-3 MOA is not atypical for USG M4/M16's. There is a reason why precision rifles use a match grade barrel, shooting match grade OTM ammo...

FWIW, I printed a 1/2", 3-shot group at 50-yards (1 MOA) out of my LWRCI M6A2 PSD Carbine (8.5" bbl) using an Aimpoint H-1 micro (4 MOA RDS) with the Mk318. IMHO, if this doesn't fit your accuracy needs, nothing will.
