Default .50 BMG wildcat

Hey guys,

I was at a gun shop the other day and was quite surprised and interested in what i saw. It was a .50 BMG case necked down to .30 cal, i just imagined what kind of velocities it would reach, it was most certainly an interesting wildcat thats for sure. Anyone here seen one before?

Proud to be a Sporting Shooter.

Over the years there have been wildcats made out of just about everything there is. Had a friend that had a 50 BMG necked down to a .17 cal bullet (as a gag). Have also seen 50 BMG with a sabot, driving a 30 cal bullet. Things is, the 50 BMG has about the best ballistic coefficent of any bullet (posible exception- some of the VLD bullets) You do run into an upper limit of speed, where lead bullets start to fly apart from the speed of the spin. Solid bronze or copper might work around that some. But then you have to answer the question- "Where the heck am I gonna shoot this thing?" Unless you have an artillery range, may be kinda hard to find a place to make go bang!

There are really quite a few wildcats based on the 50bmg case. Many of them never make it into anything other than a discussion starter. Can you imagine the throat erosion on that thing.

I talked to a guy that necked the 50 BMG down to 6 mm. It was years ago, but if I rember correctly, he said he was getting around 5,000 fps. I know he was not happy with the velosity he got for the amount of powder he was burnning.
