For expediency sake, the 10mm Magnum brass is really the way to go. 30 Remington case (if you can find them) or the 6.8 x 43 SPC base, but we found the wall thickness to be such that it would require neck turning. The parent case is the 10mm Magnum case from Starline and a simple pass through the full-length sizing die will do the job. Currently, we offer complete AR-15 upper assemblies in this caliber, as well as single shot and bolt action rifles and we are working on the prototype AK-74SU version.Īctually, since formed brass is not yet available, forming your own cases right now is the ONLY way to get brass. In addition, it allows both high velocity and subsonic loads in the same system and delivers more energy on target than some of the competing cartridges like the. 338 Spectre is capable of MOA accuracy out to 500 yards. 458 SOCOM offers superlative performance at short(er) ranges under 150 yards, the. 338 Spectre was to offer a cartridge with broad spectrum application but primarily designed to deliver a heavy bullet with very high ballistic coefficient subsonically at extended distances. 358 CQB cartridge, which itself came about during the design of the aforementioned.

So if you want crazy quiet subsonic suppressed fun, look at 300 BLK. It is going to suppress about as good as 556, and nobody is doing subsonic loads that I know of with a whole bunch of success. This would likely be the more expensive route to build up front, but, wolf steel 6.5 ammo is about $0.27 CPR for range ammo, and should have hunting power out to around 400 yards with good hunting loads.
