In order to increase powder capacity, the shoulder is higher than the 6.8, and the case is also longer. The neck is sized for .224 caliber bullets.

The 6.5 Grendel bullets have a true diameter of 6.71mm / 0.264" and the case can be formed from abundant 7.62x39 cases with a neck re-sizing die, as well as fire-forming a slight change to the shoulder if using a brass casing. Many popular 7.62x39 cases are made from steel, which will not work properly for reforming the case's shoulder.

-'''[[.300 AAC Blackout]]''' - Uses military 5.56x45 (also .223). The shoulder is reformed, length trimmed, neck sized to .308 caliber. This cartridge has become very popular, and examples are available in a wide variety of styles. Bullet weights can currently be found between 100gr to 220gr, the latter of which is primarily used with a suppressor, resulting in a very quiet report while still being hard-hitting.

This cartridge is very similar to the 300 AAC Blackout, but the shoulder is slightly higher and the case is slightly taller, which allows for more gunpowder capacity when loading the lighter/shorter high-velocity bullets.

-'''[[.338 Spectre]]''' - Uses 10mm Magnum pistol cases with a 6.8 SPC bolt-face. A shoulder is formed, and the case is lightly trimmed to length, and the neck is sized to .338, down from 0.401". The 10mm rim is 0.424" (10.8mm) in diameter, and the SPC rim diameter is 0.422" (10.7mm). The .338 caliber bullets are available in weights between 200gr-250gr.

-'''[[.350 Legend]]''' - Proprietary cartridge. The head and rim dimensions exactly match the military 5.56x45 case, allowing the use of the standard bolt-face of an AR-15. However, the case has an added taper and is longer than 5.56x45 cases, so these cannot be reformed from any existing case. The nominal bullet diameter is .357-inch, but SAAMI specs allow the bullet diameter variance to be .355-.357

-'''[[.357 Auto]]''' - Wildcat cartridge. Uses 10mm magnum pistol cases with a 6.8 SPC bolt-face. The existing 357-Sig pistol is a 9mm bullet shouldered into the larger 40 S&W pistol case. The 10mm cartridge and the 40 S&W are almost identical, but the 10mm case is longer and operates at a higher pressure. This means that you can use existing 357-Sig dies to re-form the straight-wall 10mm case into a shouldered .355" (9mm), and then the neck can be sized up to accept .358 rifle bullets. This is in response to the popularity of the 300 Blackout at subsonic velocities. If the bullet velocity is capped at 1,000-Feet Per Second / FPS in order to subdue the noise of firing, then the impact can be improved by increasing the weight of the bullet. The 357 Auto can be loaded with bullets in .358-caliber, while still fitting within the AR-15 COAL of 2.260". Bullet weights are currently available between 225gr-310gr

It has a rim diameter of 0.447" which allows the use of an AR-15 bolt-face from the existing 6.5-Grendel or 7.62x39. The shoulder is trimmed off at a case-length of 1.700", with a COAL of 2.250", resulting in a "straight-wall" cartridge. It can accept .401-.402 rifle bullets (240gr-310gr) from muzzle-loaders, and also .400-.401 bullets from a 10mm magnum pistol (135gr-230gr).

-'''[[.450 Bushmaster]]''' - Uses .284 Winchester cases. Cut the length to 1.700" to form a straight-wall cartridge, from 2.170". The .284 Winchester case is very similar to the .308, however, the .284 case has a body diameter of 0.500", and the .308 case has a body diameter of 0.471". Both share an identical head/rim. The 450B is limited to 35,000-psi, which is more common in pistols, and lower than similarly-sized rifle cartridges. The 450B uses .452" diameter bullets, most often seen in the abundant 45-caliber pistol styles. The 300gr version is rated at 1900fps at the muzzle, and the 250gr at 2200fps.

However, the 50 Beowulf case is longer than the 50AE, so the 50AE cases cannot be used as a donor.

 '''Note on donor cases:''' The 7.62x51 military cartridge is known in the civilian world as the .308 cartridge. Since its dimensions are taken from the 30-06 cartridge from the 1906 US Army cartridge, the lower half of these case dimensions have been used for designing the .243 Winchester, 25-06, .270 Winchester, .280 Remington, 7mm-08, .308, .30-06, .35 Whelen, and others. Any AR-15/AR-10 cartridge cases that are derived from the 7.62x51 can also possibly be formed from the aforementioned cartridges.

-[[300 AAC Blackout]] - Uses military 5.56x45 (also .223). The shoulder is reformed, length trimmed, neck sized to .308 caliber. This cartridge has become very popular, and examples are available in a wide variety of styles. Bullet weights can currently be found between 100gr to 220gr, the latter of which is primarily used with a suppressor, resulting in a very quiet report while still being hard-hitting.

 '''[[7.62x40 Wilson Tactical]]''' - Uses 5.56 NATO cases (also .223). Shoulder is re-formed, length is trimmed, and neck is sized to .308 caliber. This cartridge is very similar to the 300 AAC Blackout, but the shoulder is slightly higher and the case is slightly taller, which allows for more gunpowder capacity when loading the lighter/shorter high-velocity bullets.
-'''[[338 Spectre]]''' - Uses 10mm Magnum pistol cases with a 6.8 SPC bolt-face. A shoulder is formed, and the case is lightly trimmed to length, and the neck is sized to .338, down from 0.401". The 10mm rim is 0.424" (10.8mm) in diameter, and the SPC rim diameter is 0.422" (10.7mm). The .338 caliber bullets are available in weights between 200gr-250gr.

-Legend, Proprietary. The head and rim dimensions exactly match the military 5.56x45 case, allowing the use of the standard bolt-face of an AR-15. However, the case has an added taper and is longer than 5.56x45 cases, so these cannot be reformed from any other existing case. The nominal bullet diameter is .357-inch, but SAAMI specs allow the bullet diameter variance to be .355-.357

-Auto, Wildcat. Uses 10mm magnum pistol cases with a 6.8 SPC bolt-face. The existing 357-Sig pistol is a 9mm bullet shouldered into the larger 40 S&W pistol case. The 10mm cartridge and the 40 S&W are almost identical, but the 10mm case is longer and operates at a higher pressure. This means that you can use existing 357-Sig dies to re-form the straight-wall 10mm case into a shouldered .355" (9mm), and then the neck can be sized up to accept .358 rifle bullets. This is in response to the popularity of the 300 Blackout at subsonic velocities. If the bullet velocity is capped at 1,000-Feet Per Second / FPS in order to subdue the noise of firing, then the impact can be improved by increasing the weight of the bullet. The 357 Auto can be loaded with bullets in .358-caliber, while still fitting within the AR-15 COAL of 2.260". Bullet weights are currently available between 225gr-310gr

-AR, Wildcat. The parent is the 7.35x51mm Carcano rifle case. It has a rim diameter of 0.447" which allows the use of an AR-15 bolt-face from the existing 6.5-Grendel or 7.62x39. The shoulder is trimmed off at a case-length of 1.700", with a COAL of 2.250", resulting in a "straight-wall" cartridge. It can accept .401-.402 rifle bullets (240gr-310gr) from muzzle-loaders, and also .400-.401 bullets from a 10mm magnum pistol (135gr-230gr).

-Bushmaster, Uses .284 Winchester cases. Cut the length to 1.700" to form a straight-wall cartridge, from 2.170". The .284 Winchester case is very similar to the .308, however, the .284 case has a body diameter of 0.500", and the .308 case has a body diameter of 0.471". Both share an identical head/rim. The 450B is limited to 35,000-psi, which is more common in pistols, and lower than similarly-sized rifle cartridges. The 450B uses .452" diameter bullets, most often seen in the abundant 45-caliber pistol styles. The 300gr version is rated at 1900fps at the muzzle, and the 250gr at 2200fps.

-Beowulf. Proprietary. The case head and rim dimensions exactly match the .44-Magnum pistol case, and all dimensions from the lower part of the case matches the 50-Action Express (50 AE), which can be described as a .44-Magnum cartridge that has had the body of the case expanded to 50-caliber while leaving the head intact. However, the 50 Beowulf case is longer than the 50AE, so the 50AE cases cannot be used as a donor.
