Would Bring To A Knife Fight: DIY 70-Cal T-Rex Rifle

December 6, 2011


This is a homemade 70-caliber t-rex rifle. It could put a hole in you the size of two yous. I kinda want one, but I'm not allowed to own guns anymore because I'm a felon. It's not fair, dammit -- I'm REFORMED (Not really though, I just tell them that).

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 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.

I want two -- one for each hand. Just kidding, I want four -- two for each of my bodyguards. "You don't have bodyguards." Hell no I don't have bodyguards, I don't even have anybody who likes me, let alone cares whether I live or die. "You sound like you're in a pretty dark place." Help I've been kidnapped and they're keeping me in a basement!

Hit the jump for a couple more shots and a video of the thing being shot.

Thanks to Jimmy T, Max and powderkeg, who agrees one bullet a minute isn't gonna cut it. ADD A BELT-FEED.

  • 1/4" Steel plate is not thick or impressive at all....

    Make one in .45-70 and it would be a cool survival rifle.

  • interesting, but practically fail. 1132 grain makes it almost twice as much as a regular .50 round ball, but it's going so slow and the barrel too short. probably isn't that accurate despite a high BC. would make one hella home defense shotgun substitute - CHUNKS EVERYWHERE.

  • I would rather buy slug rounds for a shotty. That barrel is waaaaay to short

  • I would have yelled "First!" But I haven't had it in me since I took an arrow in the knee.

    Make this a meme...NOW.
