The newly rebooted Bushmaster Firearms recently announced the launch of a new AR-style rifle chambered in .450 Bushmaster.  

Now based in Nevada after it was acquired by Franklin Armory from Remington last year, the folks at Bushmaster say they have designed the new .450 to significantly reduce felt recoil and the gun stands ready "to handle all hunts for deer, bear, and boar."

A lightweight rifle that hits the scales at 7 pounds, the new .450 Bushmaster runs a 20-inch barrel with a 1:24 twist rate. Other features include a 14-inch free-floating rail with M-LOK accessory slots, a Snake Charmer muzzle brake, and a DM2S Dedicated Marksman two-stage trigger.
 

Using a carbine-length gas system, the new .450 Bushmaster rifle ships with a five-round magazine. The MSRP is $1,329.99.

Developed by Tim LeGendre as a take on Col. Jeff Cooper's "Thumper" concept for a large-bore carbine optimized for use in a 250-yard envelope, the .450 Bushmaster cartridge was first marketed by Hornady, and SAAMI certified just over a decade ago. Using heavy bullets in the 250-grain region, it has been characterized as capable of harvesting game as large as elk in its effective range. Further, it single-stacks in a standard AR-15 5.56 NATO magazine body. Both Remington-owned Bushmaster and Franklin Armory produced rifles and pistols chambered for the cartridge in the past.
