Comparison of the 6X68 to other cartridges
6mm AR* is made from expensive brass, is a proprietary cartridge with some restrictions. Does work well with the heavy bullets. Requires custom made reloading dies.
The 243 LBC* is made from expensive brass. Made from 264LBC/6.5 Grendel cases and has some head spacing differences. Does work well with the heavy bullets.
Both cartridges hold 36 grains of water as well as operate at 52000 max pressure.
6mm BR* and 6mm AR Turbo* both hold 38 grains of water. The turbo has to be fire formed and uses custom dies. It still only works at a max pressure of 52,000
The 6 BR uses a .473 bolt which at this time is proprietary it runs at an extreme pressure of 56,000 PSI brass is expensive but the dies are off the shelf.
6mm DTI* This is an improved version of the 6X68 Water capacity is 36 grains. The 6mm WOA groups in with this one as well. It too has a 30 degree shoulder but is made by pushing back to form it. In doing this some case capacity is lost from the case's original form. It is proprietary and requires fire forming and a set of custom dies.
**With Straight walled cases and sharp shoulder angles these cartridges tend to have issues in lipped magazines which may result in some feeding issues.
The Benefits of the 6X68 Cartridge
Easy to make with off the shelf dies. Water capacity will be more than the WOA and slightly less than the DTI. Estimated at about 35.8 grains. Does not require fire forming. It will give you the ballistic advantage of the proprietary cartridges listed above without the cost of and limitations of making and using a proprietary cartridge. Commercial Ammunition will soon be available from Tactical Ammunition and for those who wish to reload components can be purchased off the shelf.
We have chosen to bring it out on the market, free and clear, without proprietary restrictions for the enjoyment of the public.
If the interest is there, we are considering a group buy to kick off the production of this cartridge.
The group buy would be a complete upper in the buyer’s choice of 18" or 20"
Black Hole Weaponry barrel. Each Upper will be assembled by Ritch Johnson with parts supplied by
New Frontier Armory. Every upper purchased will include starter Ammunition supplied by Tactical Ammunition.
