Lol. Always use enough gun.

I wouldn't want to have to pack one of those or put it up in a treestand- maybe you can get a chainhoist?

The only one I've ever shot or ever seen for that matterbelonged to a guy who built it himself by machining his own receiver, using a surplus M2 barrel, he had machined a muzzle brake that was roughly the same shape and size as a coke bottle,and I think he cobbled the stock together as well- I remember seeing duct tape to hold the cheek piece on. This beast had to weaigh 65-70 lbs, it held very nice and steady and had very little recoil but an amazing muzzle blast. I wish I had one of those toys.[8D]
