300 AAC Blackout/300 Whisper side by side
 

Here is a side by side comparison of Remington 220gr 300 AAC Blackout and Corbon 220gr 300 Whisper. They both feed like a champ in my Model 1 16" upper. As you can see the 220 300 Blackout is shorter than the Corbon. It seems to feed faster like the Corbon 150gr(not pictured), as compared to the longer 220 300 Whisper. I'm thinking the 220 300 Whisper is more accurate in my rifle because the bullet is closer to the rifling.
300 BLK: 220gr. --- 300 Whisper 220gr.
Case length: 1.355 --------- 1.340
Neck dia. .332 --------- .332
OAL 2.090 --------- 2.214

All that reamer talk was someone making a buck, cause they are the same. And Model 1 said not to shoot it. But they are idiots there. Just covering their ass for a new product they no nothing about.

Why it took this long for someone to compare them I don't know. I just got my BLK's today.

Nice first post Idge....:welcome:

The reamers are not the same. They can't be, as I never saw a 300 Whisper(R) reamer drawing when we came up with the 300 AAC BLACKOUT chamber specs. So what are the odds they are the same?

We tested longer OALs and beyond a certain point they bind up the AR magazine. But you may not notice this if you don't fill 30 round magazines or shoot thousands of rounds of ammo.

Welcome Idge
 

Welcome to a great place to learn. I am glad you posted the pictures side by side. I have been a 300 whisper snob for to long but have seen the light. Now its whatever floats your boat so long as its a 300 WTF, doesn't seem to be more than a hair's difference between any of them. The 300 AAC is nice for the folks that don't reload and now have an option other than Corbon.

Thanks guys. Iv'e learned a lot from the posts here.:smile:

When I watch the ammo feed into the chamber, the shorter ones feed a little smoother. I think that's why the BLK(SAAMI) has a shorter OAL than the Corbon. But the Corbon 150 Supersonic rounds are about the same OAL as the Remington 220 Sub's.

Pretty darn close, huh? Are the Blackouts any cheaper than the Corbons?

Yep
 

I believe the the blackouts are cheaper by 1/3 I think. I bought Corbons for a year and never got to enjoy my rifle as everytime I pulled the trigger I am thinking ouch $$$. I bought some hornady dies from SSK. 500 brass from Hoser. Now I am a maniac, shoot squirrels, groundhogs, paper, deer, whatever I want, whenever I want. I get to play with different loads. Never think about the cost at all. But,,,,,,I am shooting a single shot encore. I cant imagine shelling out for cartridges spraying with an AR,,, at least not on a hunting outfitter's income.:smile:

Remington 300 AAC BLACKOUT is $12.99 MSRP for supersonic (though the design is being tweaked before more is made), and $21.99 MSRP for subsonic. CorBon is currently about $40-$45 a box for either.

Yep...I'm in the wrong tax bracket to buy CorBons...that is an affordable "storebought" alternative....why are the subs so much more though?

The 2 reasons I can think of are componet cost and thats the desired round so they are more expensive. But I seriously doubt 220 smks cost $9 more for 20 pills compared to the 123 gr lmfao.
