Wouldn't shooting any of the bullets on rsilvers list meet all five of his criteria better if shot using a 300 OSSM cartridge or even a 7.62x39 Russian? Pardon my blasphemy...

I agree, any of these out of a x39 based round would be tons better for deer ect.

110 grain. Why do you like heavier bullets? What does a heavier bullet accomplish? You want to ensure sufficient penetration? This has it:

It depends on the bullet. A 110-VMAX would not be good at higher velocities as it will just blow apart and not penetrate enough. On the other hand, a 125 Nosler is a bit too tough for lower velocities and probably would be better from a 308 (but not necessarily a 300 OSSM).

The best thing about this bullet is the shape and length - designed to have the ogive rest on the magazine rib and be as long as 5.56mm when loaded. The UMC bullet does the same thing. As does the Remington 125 Match bullet. As do 6 more bullets coming out in 2012. Each of these are or will be the best bullets of their kind. So 9 optimal shape custom 300 BLK bullets.

The black tips are just the color we preferred for BLACKOUT.

At lower velocities, 308 smaller game or varmint bullets (110-125 grains) penetrate deeper than what you would get from a 308, and so start to behave like a medium or big game bullet.

You can see this from the gel testing I had done after starting this thread:

http://www.300aacblackout.com/resour...t06OCT2010.pdf

For this reason, you have to toss your sense of what constitutes a normal bullet weight.

The argument for more case capacity is for greater range, not higher terminal velocity. Each bullet has a window of terminal velocity which is target dependent where it gives it's best performance. The muzzle velocity, bullet BC, atmosphere and range determine the terminal velocity of any bullet.

A quick calculation says a 110 grain bullet in a 24" 308 would give about 3300 fps muzzle velocity. I'm just guessing at the BC but that should give roughly the terminal performance at 300 yards as the 300 BLK near the muzzle. I think the 300 BLK is the best subsonic cartridge on the market. I just don't have a use for it for supersonic shooting. For many hunters with suitable game at short range it may be ideal.

rsilvers:
Can you give us the dimensions and BC for 110 Barnes bullet? Is it a "lead free" design? So the back tip is a poly insert in a large hollow point? It would be nice if SAAMI would standardize what tip colors mean like NATO does.

I really like the way you present your test results with bullet photos and barrier + gel penetration measurements. What thickness is the door steel, plywood, and drywall?

Agreed that starting out at a higher velocity gives longer range for any given bullet.

The plywood and drywall should be whatever the FBI uses - that is all standardized. But I also don't know what it is.

I don't have an exact BC, but it should be about 0.300.

The bullet is designed to be loaded to a nominal 2.245 inches OAL and perfectly rest against the rib. That is what I had done to a whole slew of bullets (the UMC included) from several manufactures.

The black tip is plastic. The bullet is solid copper. The tip is unusually large to allow for a larger cavity to control penetration.

While solid copper bullets are not cheap, there will also be plastic-tipped jacketed-lead bullets with this profile - its gonna be great.

Every company has their colors. Barnes are usually blue. Nosler has everything. Hornady is normally red. Swift does a lot of black.

Part of the reason why this tip is black is because the first ones were lathe-turned while the plastic injection molds are being made - and Delrin(R) comes in white or black.

We have been using red primer sealant on supersonic and blue on subsonic loads.
