50 Cal Is For Girls – Check Out This DIY 70 Cal T-Rex Rifle

By David Ponce

Used to be that if you were serious about shooting, the .50 caliber BMG round was the way to go. That sucker could propel an 800 grain lead bullet (that means 52g) to 2,900 ft/s and put an eye out from over a mile away. But that’s not enough; some folks went and made their own rifle and their own ammo and created this monster that uses a 70 caliber bullet. Yes, that does mean that it’s 0.7 inches across.

The cartridge, named the .700 WTF (“What The F…”) and is made by fire forming a .50 BMG brass case, trimming it to 3″ in length and then sizing it. The round is loaded with a 1132 grain (that’s 73.58g) paper patched .700 lead cast bullet.

The rifle, with just a 16.25″ barrel, can push the 1132 grain of lead up to 2300 fps. Thats 13,000 ft/lbs of energy, right up there with the .50 BMG and far exceeding the .700 Nitro Express. The cast lead bullet has enough energy to pass clean through a 1/4″ steel plate.

Well, it has a little more energy than that. It goes through the plate and lodges itself a foot deep into a tree stump. The recoil on that thing makes it look like Chuck Norris kicked you in the chest.

Hit the jump for a couple more pictures and an excruciatingly bad video that’s good to watch only because you see this rifle in action.
