The max the brass can be for 300 AAC BLACKOUT is 0.334 on the neck.

Obviously I did not say it was completely different - I even told him that he may not have to change his chamber. He heard what he wanted to hear.

I commissioned gel testing of most of the recommended bullets on this site, and will release the complete report here for everyone to see and learn from.

rsilvers,

My comment was not directed at you. It was directed at the corporate PR people who always say whatever the product is they are pushing that it is brand new never been done before, greatest thing since sliced bread. You did say the chamber may not have to be changed but you did not simply say you took the 300 Whisper and standardized or massaged it. I imagine you didn't because the powers that be would have a fit if you came out and said it's a 300 Whisper.

Our THUMPER line of cartridges is new to us and I don't remember seeing them before I came up with them, but I have read Cartridges of the World about a zillion times and the 338-223 Straight is in there. As much as my partner hates it I would never say that I designed it or even came up with the idea of it. I trying to learn all I can about subsonic rifle cartridges I find myself going back to the black powder and early smokeless powder cartridges for some great information. Like many things we are just coming full circle and relearning what people used to know.

think of it this way, you had a hand in developing a new mass released cartridge:wink:

We wanted to create a uniform standard and then let anyone use it royalty free. If we called it 300 Remington Fireball, many would think we would be saying it is compatible with all of the 300 Fireball wildcat reamers - and we are not sure it is. Most people already know this is a good thing for major companies to make more products, and those who don't will come around once they see the ammo prices. We have a lot of ammo being made before the end of the year - way more than 6.8 SPC ammo - probably more than all 6.8 ammo combined from all companies that make it.

so, you are saying it should be compatible with many chambers, or could be with 15 minutes& a touch up reamer
edit to add, It sounds like you have some ammo makers lined up, will they be re-purposing once fired brass, or making new? will it bear the 300blk head stamp?

My business partner bought one out of the first batch, going to get my hands on it soon.

And yeah, going to be testing it to see if it will work with ammunition loaded off my .300W dies......

IIRC so far only Remington is lined up to make ammo. Although, any ammo maker can without paying any royalty fee. The 300 AAC BLACKOUT or 300 BLK names can be used by anyone that is meeting SAAMI specs. I believe I read that the Remington brass is head stamped 300 BLK and brass will be available some time in 2012. Till then reloaders will need to make it from .223.

Honestly I think it is smart. Find out what works and what people in the know want and then market it. I prefer that to a company that makes what they want and doesn't pay attention to what customers are asking for, which has been the case with large firearms makers in the past. I would expect a company trying something like this to do research first and that would include talking with those that have been there and done that.
