Pretty cool that he's hanging with us and sharing his expertise.

If you're truly the project manager, you'll have the sales projections. Are you genuinely telling me that it's 40%+ of the AR-15 market in the next two years?
The bigger issue was the chamber & case drawing screwup.
It was bad enough the Remington submitted design had less freebore and a much sharper angle where the neck transitions to the freebore, than the original chamber of the 5th SFG; but if you look at the drawings you can have a conditon where a case 'in spec' to the max dimensions would not fit in a chamber that was 'in spec' to the minium dimensions.
I'll buy into that prediction.No. I would not forecast that much. I do think it will be the #1 alternative centerfire rifle AR cartridge within the next year.
rsilvers, is the only difference between .300blk and .300WT the cartridge length. What is there to recommend one over the other?
7.62x40mm is not a SAAMI round, so larger companies won't make products for it. There is one or maybe a few companies working on it, while 300 BLK has about 90 companies. 7.62x40mm has less of a taper, so it has to be fire-formed to make the brass in-spec if you start with 223 or 5.56mm brass - a very costly step for reloaders as it requires firing a bullet. The cartridge is not compatible with standard magazines unless you download them to lower capacity. It has a very short neck length, so there is, in my opinion, not enough bullet support. And while it is claimed to be 200+ fps faster than 300 BLK by some users - that is only if you load it to well over 55,000 psi. If loaded to the same 55,000 psi pressure as 300 BLK, then it is more like 85 fps faster with 125 grain bullets. While fans of it have said it is better if you want just supersonic ammo, I don't see it that way - for the reasons listed - even for just supersonic use.
I really need to stop reading these threads. Now i want to build a suppressed .300 BLK. My wife is going to kill me!!!
Welcome to the jungle baby! This place will feed your addiction.
Just curious, what would be the implications for a small (85 grain) pistol bullet or 100 grain rifle bullet. Would this be practical for a supersonic load with increased velocity in the .300 blkout?
Just curious (and a little stupid).
The bullet would be too short to feed. 2.1 inches is the shortest OAL that is very reliable in an AR - same as 223. You can go shorter if reliability is less important, or if you are using a single shot or bolt-action rifle.
