Introducing the 400 BTS Mag!

Whats a good price found a low round count Stevens 200 for 275 shipped if he still has it?

[475AR]

PM me and I will forward you the info. (I do not want to hijack BT's thread.)

Good stuff! Couple questions:

Are AR10 parts and AR15 parts pretty close on prices? I assumed AR10 stuff
would be more expensive.

How does your 40 supersuper mag at AR15 pressures compare to 10mm mag?
If they are pretty close it might be easier for me (my experience level) to just
work with the pistol cartridge (straight wall).
I'll look up 10mm mag later after work, not familiar with it.



The Savage bolt action setup sounds tempting, might save on gunsmithing!
Maybe I'll spot a used one.

BT I shoot a 6mmBRX in an AR15. Uses a .308 Bolt face and special barrel extension. Harrison at
http://www.AR15Performance.com/ makes them. Using some 6.8 SPC mags you can load to 2.30 inches.

Yeah, that is my nighttime lead dispenser. 18" barrel, and barely 26" overall.

With the Gen III sight you can call a 'yote in & the only light is the muzzle flash.

The barrels are not all that hard to change - a bit like the savage with a gas system. A new barrel may be in it's future.

Think you could make this stuff work? http://www.castpics.net/LoadData/7383/default.html

That Savage is sweet Brian. I love how easy they are to work on.

Thanks, but I would have to fuss with that load a lot - an adjustable gas 308 will shoot all kinds of stupid stuff. It will cycle Remington accelerators.

I need to get busy and make a vortex flash hider for it.

Yeah, it sounds like some very fussy stuff, but having nearly no flash is an interesting thought, I only found out about the stuff recently. I want to get some night vision capability first tho. Your setup looks pretty cool.

Wow, very impressive work. I love watching the development going on. I'm just a lurker for now, I'm just doing my research prior to getting into swaging my own. BT- I have some 300 wm to donate if you run low, call it the price of admission to a wonderful show!

Bump for interest. I know your busy Bryan. Just came up on 300blktalk.com about .400Blackout based on .308 case. I linked this thread. Fwiw, I think this would be a great solution to one man one caliber(kinda) and multiple platforms. I see the 40.08 being a good alternative to the .358W as a brush popper with heavy bullets and with light(160grs) bullets a very capable mid range rifle. Anyways, hope you can get back to the project soon.
