I was watchin the hunting channel today and there was a guy using a rifle that was a .500 Jeffries necked down to a .30cal 204gr a-max i think it was. Does anyone know anythin about this setup? said it was shooting about 3450FPS..... gun)

For sure it would be a barrel burner! I believe that the .500 Jeffrey case is in between the 416 Rigby and 505 Gibbs (Cheytac) in size and capacity. Interesting.......lightbulb
 
I love pigman, my kids and i watch him every week, i too have been trying to get some info on that gun. i think he has both a 300 and a 338 version, he shoots 208 grain hornady amax. i think the advantage is that you can use a lapua action instead of the cheytac action and get similar performance with a lighter set up. i own the 338 cheytac version and it weighs alot around 14 pounds scoped. i just sent pigman an email hoping that someone will respond to my email about the gun. gun)
 
Haha yea pigman thats it! I was very impressed with the long range shot with that stout of a wind! That speed goat had no idea what hit him. Sure looks like a fun rifle to shoot thats for sure! I bet they cost a grip tho.... be interested to findout what "pigman" says! :D
 
taped it and watched it he said its called the king hog shots 125grs of powder and a 2?? at 3400 to 3500 anyone seen one yet or know the smith doing them.
 
The 500 Jeffrey has a Base diameter smaller than the 338 Lapua! I would imagine that the case was shortened or left as a novelty and at best velocities would not make the popular larger 30 cals blush one bit. Over bore capacity pretty much hit its crazy limit with the 30-378. Brass such as the 50 BMG has also had 30's stuffed into it. It sounds really powerful though and that is what keeps some of the shows going. One show in particular could be renamed Beavis and Butthead.
 
so the guns are made in douglas wyo buy twisted barrel. the gun the pigman was using is a 300 shots a 208 at 3500 plus. there is also a 338 built by the guy and it shots 250 at 3500.
 
Those velocities are up there no question about it. The 30-378 is good for 3200+ with a 26 inch barrel and a 200 grain bullet. the 338-378 in 250 grain about 3200 with a 26 inch barrel. start adding barrel length and the velocity differences start vanishing in a hurry and that is in a factory out of the box chamber dimensions. I think that he may have access to some of the super magnum powders such as reloader 33 that have not hit the shelves for the general public yet and that alone is worth 150 fps ( according to information released at the shot show) I don't believe that any exta ordinary velocities can actually be assigned to the 500 Jeffery in those bullet weights, diameters and might only be significant in the heavier weight bullets in the 338. Apples and Apples, Oranges and Oranges, pressure for pressure and barrel length for barrel length. Even bullet coatings, but see it as a good wild cat in larger diameter bullets because it already is.
