![]() ![]() ![]() However, aerodynamic drag is higher on a stubbier bullet, so down range performance suffers significantly. 308 bullets are used to maximize the powder charge in the case. To overcome this problem, relatively light and stubby. The downside to this approach is the diminished case volume for full power applications. 300 Blackout dodges the problem of excess case volume by using a. This fills the case, but the burn rate of this powder is very fast such that the pressure generated in the barrel is insufficient to cycle the action. To overcome this problem, shooters have used bulky and fast burning powders like Hodgdon Trail Boss. When combined with our 200 grain 6.8 BSP bullet and the right powder, like Hodgdon H4895, the 6.8 SPC case has very little empty space.Įmpty space is a common problem when loading subsonic rounds like the. The 6.8 BSP AdvantageĬase volume makes the 6.8 SPC an ideal base cartridge for subsonic applications. When operating with full power 6.8 SPC cartridges, the 6.8 BSP clearly dominates the Blackout by every measure, including muzzle energy, down-range energy, trajectory, and effective range. 300 Blackout’s edge disappears quickly when things speed up. Because muzzle energy is linearly proportional to bullet mass, the Blackout does have a slight advantage in muzzle energy when operating subsonic.īut the. ![]() The Blackout shoots 220 to 240 grain bullets when operating subsonic, compared with our 200 grain 6.8 BSP bullet. The closest competitor to the 6.8 BSP is the. The 8.5" barrel is available HERE or you can build it into an upper assembly HERE. The 11.5" barrel is available HERE or you can build it into an upper assembly HERE. The 16" barrel is available HERE or you can build it into an upper assembly HERE. We currently offer three different barrels and upper assemblies for the BSP: The key to the 6.8 BSP is the combination of the heavy bullet and barrel with stabilizing twist. The 6.8 BSP takes advantage of the properties of the 6.8 SPC cartridge to provide the ideal platform for dual suppressed subsonic and full power applications. The purpose of this configuration is to create an effective combined subsonic / full power platform for hunting and tactical situations. The Bison Armory 6.8 BSP consists of a 6.8 SPC caliber barrel with our custom 6.8 Bison chamber, a fast 1:7" rifling twist rate, and a 6.8 SPC cartridge loaded with a custom made 200 grain bullet. ![]()
