300 AAC Blackout/300 Whisper side by side

[Idge]

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:

[rsilvers]

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 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.

[Idge]

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?

[martineta]

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:

[rsilvers]

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?

[Titleiiredneck]

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.

[martineta]

Check the prices for 220, 230, or 240 gr sierra matchkings and you will see why the subs cost more. Want to be further shocked. Check out the 240 and 225 grain Outlaw state bullets. I love the 225 gr outlaws to hunt with but at $1.25 each for just the bullet, a tad rich for plinking but great for killing. IMHO.

[Titleiiredneck]

I did, $190 for 500 220 gr so thats $0 .34 per round or a tad over 7 bux per 20. Now back out the cost of 123 otm and tell me its $9.00 more to produce this ammo per box of 20. Its nothing more than rem making a few extra bucks off people who donot reload because we all know there isnot a $9 diffrence in manufacturing costs even if remington paid $190.00 per 500 for 220gr smks " which they arenot".

Redneck,

The long Sierra bullets are challenging to load, and the machine has to run slower. Even if this were not the case, you can't just take the difference in cost to us and say that should be the difference in MSRP. There is having to buy the bullets and have that money tied up until the sale, and then margin has to be added. On top of that, the 123 bullets are made by Remington, and so cost much less.

Sierra bullet 308 ammo costs like $30+ a box MSRP, so $22 was us trying to make it affordable. It is literally 1/2 the price of the competition.

And 168 grain bullets from Sierra cost a lot less than the 220s.

The 220 is not padded in price because it is desirable, rather the 123 has even lower margin to have one load as promotional ammo to give people something to shoot.

[martineta]

In the words of my dear old Daddy ,,,Raise the prices until the players start to leave the table.

What we learned in Grad school, first day of finance class.

A company reason of being is to Maximize the return to its investors.

I believe it to be true.

[Idge]

My simple little test of the two different 220 factory loads available is done.

I'll be hunting with the Remington 220 Blackouts. They feed and eject flawlessly. The Corbon Whispers don't. I am going to seat the Corbon Whispers deeper like the Rem. Blackouts and see if that helps them in my AR platform. At 42 Yards the 300 blackouts were hitting 2" high. Right where they need to be for a 80 yard zero. The cool part is the 150 Corbon Whispers our hitting right on the money at 40 yards. Which should put it about right at 80 yards too. If I want to use them. One point though...One of the 150 Corbon Whispers primers blew out of the shell and it didn't eject.:eek:

[martineta]

Before my dies arrived, I bought 3 boxes of corbon 220 subs and 3 boxes of 125 supersonics. The 125s did great but those darn 220 subs would not fire about every 4th or 5th bullet. I bought them on sale "Cheaper than Dirt" and figured afterwards they were on sale for a reason. When I got my dies, I took out the bullets, knocked out the primers, reloaded and all worked as they should. I got a bad batch IMHO.

[Ned christiansen]

I've found the Remington 220's to be very accurate and functional. My experience with the CorBon 220's was the same, but I have not shot as many. The RUAG 220's grouped well-- but only one box's worth of experience, and they had to be fired from a Blackout chamber-- too tight in my Whisper chamber.

I do totally believe in the shorter seating depth of the Remingtons as far as eliminating magazine issues. It just makes sense. The Remingtons are also just a tad hotter than the other two, while still being subsonic, helping function. Fired side by side, the RUAGs and CorBons seem quite light.

But then sofar so good with the Hornady 110's and 208's. My understanding from Patrick Sweeney is that the 110's do well in gel.

My solution for econo-loads is cast bullets.... Oregon Trail gas-checked 200 grainers have worked very well for me.

[Idge]

I noticed that the Remington's were hotter too. Do you think it is because the bullrt is deeper? Because, I pulled the bullets and weighed the powder. Of course I don't know what either one is. But they both look like real fine powder like H110. The Remington's had 8.9gr. and the Corbons had 9.9gr. Any one know what powder they each are using?:uzi2:

[LouBoyd]

How about some chronograph readings?

What would be really good woud be to write the velocity of each shot on the target pointing to the point of impact of each shot and post a picture of the target. 100yd preferably.
like #1-1030 #2-1045 etc

Use a eparate target face for each cartridge model and rifle. 5 shots would tell a lot. 10 would be better. Carefully aimed of course without readjusting the sights.
Include on the target the barrel mfg, length, twist, range, ambient tempearture and elevation. Note if the first shot is cold and or clean bore.

I'm sure not everyone will get the same results with various chambers, throats, and shooting environments. A pix of the shooting setup with the rifle and chronograph would be a nice addition.

[bubbadad]

so for all practical purposes i can shoot blackouts instead of whispers thru my whisper barrel? use blackout dies instead and still have a good cycling and accurate shooting gun.:nanabang:

[Idge]

I would if you want it to cycle every time. I will be chronographing the end of july. Have fun. I love the .300's even if I would have to shoot one at a time anyway....:nanabang:
