Just want to say I called it! This is exactly the cartridge Winchester needed to release after the .350 Legend's surprising success. An updated version of the old .401 Self Loader. It's a 6.8spc parent case necked up to .40 caliber. With all of the .40 caliber bullets on the market for the 10mm this was really a no brainer.
This cartridge will really turn an AR-15 into a hog and black bear thumper. Loaded up with some 220 or 230 grain hard cast moving north of 2000fps without the magazine capacity limitations of the larger .45 caliber cartridges now avaliable. I think it's going to be a homerun.
