Home Forums Hunting & Shooting Hunter's Campfire 270AR SPR (New AR-15 cartridge coming this fall)

Its not a standard bolt its a 800 series bolt made with 9310 alloy and it will run in 6.8SPC PRI mags and yes will work in a standard upper.

So, I guess Newton was "guessing" according to your intellectual way of "thinking".

Never seen a deer killed with a falling apple.

Bullets matter far more than headstamps, placement trumps charts.

I'll take a 223 over a 35 Whelen for deer hunting everyday of the week, but that's based on hunting use, not HIT charts and physics.

Since it has a 0.473 bolt face I'm guessing it shares the body dia of the 458 SOCOM, which feeds single stack from AR mags. This is where the added zip comes from. All this really obseletes is the WSSM uppers, and since brass for them was/is problematic this is a step forward. Basically turns your M4 into a four pound sniper rifle (added weight of the second upper) plus mags and ammo.

The 30AR is a great round but is not a standard AR-15 as in does not use standard AR-15 parts. I can't build it at home and they are in pretty low production and hard to find but still produced unlike what is commonly reported online and it forum chatter. I prefer a AR-15 i can build myself. This 270AR has the same powder capacity as the 30AR but fires a .277 bullet. The only difference from the 270AR from any other AR-15 is the bolt and barrel. No specialty uppers or lowers.

For hunting there really isn't a comparison, the 30AR trumps them all.

I've never used one, but I've read enough about it to know it is better.

Maybe Sir Isaac will chime in on his 30AR experience.

seems to me it solves a problem that doesn't exist but in folk's minds

The 30AR really isn't an AR-15. I guess i should have been more specific though and say it beats mid caliber AR-15's.

Damn you're dumb.

So what is "handily"
At what distances in what winds? With how many foot pounds.

How much ACTUAL velocity are you getting? Vs what they proclaim?

Not saying it won't be a good round. But i hardly see anything 200 fps faster than an existing round( if it gets that much) in the arena of cartridges we are talking about as being as a "game changer"

Of course I'm also of the theory that while I have other rounds in the AR, and have shot ARs for years and probably logged more than the average AR shooter round wise, a 223 and tsx bullets do awful good to awful long distances for most folks.

Ok this post tells me a LOT.

I'd wait.

I'm a fan of ARPerformance for standard AR lowers but if I'm shoehorning the longest widest cartridge I'm using the longest, widest mag-well. LWRC promises to open source their enlarged mag-well Six8 so expect other manufacturers mag-wells to get bigger also.

The Six8 uses a poly Magpul 6.8 mag with interior OAL of 2.32". Now someones going to come along and build a steel or aluminum mag getting the most out of the new mag-well dimensions. Those dimensions have yet to be made public but for all we know .473 diameter brass might double-stack in such a mag, and the interior length without the poly could easily be in the 2.4" neighborhood.

If it's a 270 Titus equivelant I would vouch for it's effectiveness based on a sample of...1.

I'm saving my pennies for a stretched AR10 in .338 Lapua.

And a Sharps .45-90

The max loads typical with a 6.8 SPC are in the 27-29gr range. The 270AR is in the 39gr range and its shooting the exact same bullets. That should be a clue. The 200FPS jump is a very conservative polite estimate.

I thought that magwell and those mags looked bigger, I was in the sandbox and didn't have a dial caliper to measure them though.

Nice Blacktail!

Thread HiJack-
We got my buddy Jim this one 100 yards from the first one the next fall. Still one more there this year for me.
