Knight Rifles "Americas Muzzleloader" head to the range to test fire the largest and most powerful center fire rifle ever created, the .950 JDJ It fires a 2,400 grain bullet with 240 grains of powder! The rifle featured in the video is one of four, and the only one that weighs in at 50 lbs All the others have been beefed up to over 100 lbs to help settle recoil and improve accuracy. I can't even imagine firing one of these, I'm sure it's an unforgettable experience. The bruise on your shoulder would be a reminder if nothing else. Check out the .950 JDJ!
