I got an email from M1S on this and their chamber throught is shorter than the 300 Whisper. DO NOT use 300 BLK ammo in a Model 1 Sales 300 Fireball chamber - you will have excisive preasures.

Rsilvers, does the 300 BLK use large rifle primers?

Also, how did these loads do in the ballistics gel? Was it over-penetrating?

I just tried to order a couple of boxes for testing from midwayusa but it's on backorder. Sigh... Oh well, so's the AAC 700 barrel. I've got other rifles to shoot while I wait.

Could you tell us how these loads differ from the Corbon subsonic "Whisper" 220 SMKs Such the difference in cartridge OAL, 16" barrel velocity, and pressure curves? I realize you probably don't want to publish actual loads with powder type and weight, though that would be helpful to shooters.

The ammo was in stock when I posted it, but they were down to less than one case.

The AAC 700 barrels have been at AAC for 7 weeks now. You have to call to order them though. Putting an order in the computer generates a work order to assemble the barrel assembly, which entails screwing on the thread protector.

I don't know how it differs from Cor-Bon ammo. I have a box of Cor-Bon, but I never tried it. Remington OAL is, I think, 2.089. The velocity is 1010 fps from a 16 inch SAAMI test barrel.

Interesting. I'm personally leaning towards a LFN boolit for the best terminal damage, until the jacked bullet companies design a softpoint to work in this fps envelope.

If my understanding on the matter is correct, the leading edge is really the big deal in supersonic flight, but the trailing edge becomes less minor in subsonic. I'd be very interested to see if any on the more boutique bullet companies come out with a ~220gr rebated boat tail jacked soft flat nose (RBTJSFN?) designed for the 300AAC. Maybe evening something of a borerider (if you can due the with jacketeds) to decrease the bearing surface. Wake me up, I'm dreaming. Maybe I just need to read up more on shooting boolits with suppressors.

Dannix,

Make sure when using lead bullets with a suppressor that your suppressor can be taken apart to clean. Most people say it is lead buildup but it is not. I shoot predominately lead bullets and took all the buildup from my Uzi SMG suppressor and tried to melt it down to see how much of it was lead. The pile started out to be the size of my fist. I got a piece of lead smaller then the size of a quarter, the rest was all burnt powder and bullet lube.

I know this is a shameless plug for my suppressors but all my cans are take apart so they are cast bullet friendly. I do not have anything on my site about it yet but I do have a can for the 300 whatever we are calling it today. It is the same can with a smaller hole as our 338 THUMPER suppressor. We are currently working on trying some other materials and coatings for it to make it super light. We are also working on an integral suppressor for the Whisper.

Dannix,

You have it backwords the key to reducing drag on a subsonic bullet is the base design. At subsonic velocities air drag is caused by base drag. A rebated boattail can improve ballistic co-efficiency by as much as 40%.

I'm just hoping that Remington will offer these projectiles to us handloaders soon. Been looking for a budget jacketed projectile in this weight range.
