With all the wildcatting and subsonic wildcatting going on with the AR platform, I was looking forward to some AR10s in .338 Federal.  (.308 necked up to .338 projectile)  Bullet selection is pretty good.  300 grain Sierras at 950 fps wouldn't be anything to sneeze at.

Armalite and DPMS make them, there might be others.  Problem is the .338 Federal just isn't popular, even though is a fine cartridge.  I've got a T/C Pro-Hunter in .338 Federal, but the ammo prices and avalibility are outrageous.  I've been looking for properly headstamped brass for 2 years and haven't found any yet.

Can you fireform your own out of .308 brass?  ETA: I understand that's not what you were looking for, but just wondering for my information since I have a pile of .308 brass.

Price check on .338 suppressor.

$200 and a Form 1

I always thought a SOCOM16 would be sweet in 338.

With regard to the parent case, the .308 Win, there are two more calibers that are very popular in longer cases but missing in the short offering.  The .277-08 and .257-08.  That always seemed a bit odd to me.

As for .338, I think it is an irrational fear of recoil.  The vast majority of hunters consider .30-06 / .308 Win to be the upper level of shootability.  .338 is bigger than either one of those, so it has to kick more

I've never seen that.  In fact, I hear more complaining about recoil from Arfcom than any hunting circle I run in.

Why not go with .260 Rem?

I've seen a following of the 25-08 but the nonexistance of the 6.8-08 is baffling. The 6.8 is the "American"  7mm , the 7-08 is the equivelent of the 7x57 , one of the finest cartridges of all time.

Because going subsonic with it defeats the purpose.  If you limit velocity, you want to stick the largest projectile in the case as you can.  .260 Rem is a fine long range, high velocity cartridge.

375 Forsberg would be excellent for subsonic work.

Gotcha. 300 Whisper not heavy enough?

If you kept the load sub-sonic you could use a 9mm can.  (confirmed this with SWR a while back)

220 grains vs 300 grains.  More whomp but splitting hairs probably.  I wouldn't want to get hit with either.

Well, that's kinda the point of my question.  There's a lot of work going on in the .30 projectile - .223 size case, which is great for an AR15, but you're really limited to what, 220 grains?  And none of them are factory offerings really.  Then Federal releases the .338 Fed, which should be an excellent hunting round, match projectiles available up to 300 grains, and would fit in an AR10 magazine with probably no alterations.  A device like a Noveske switchblock and you could go from subsonic suppressed to full power unsuppressed at a whim.

Just seems like a great combo to me in theory, but like mentioned before, there's little factory ammunition available, so maybe that's part of the problem.

I guess I am thinking the whisper has more support and suppressed shooting research behind it.

ETA: is .338 Federal just a barrel swap away on an AR10 platform gun?

True- If you really wanted subsonic .338 in an AR platform I think a .338 Specter or similar would be a better choice for that reason.  Other advantages are a lighter firing platform (AR15 vs AR10) and cheaper parent brass.  The .338 fed would have more potential for hotter loads though.

Should be.  Not sure about the mags though.
