How about the .257/7mm STW. Sometimes called a .257 Ferguson Hot Tamale? I have read a lot about this cartridge. It is a wildcat many have built, but James Ferguson in south TX is the most notable. He claims to get 4000 fps from a 100 gr .257???
The following is from an article by Russell Thornberry:
My rifle was zeroed at 350 yards. With a muzzle velocity of 4,060 fps, my 100-grain, all-copper J-36 bullet (manufactured by Lost River Ballistic Technologies Inc.) with a ballistic coefficient of .532, registered as follows:
+ 1.89 inches at 100 yards
+ 3.15 inches at 200 yards
+ 1.78 inches at 300 yards
Dead-on at 350 yards
- 2.58 inches at 400 yards
- 10.27 inches at 500 yards. /ubbthreads/images/graemlins/shocked.gif
Incredibly, the velocity at 500 yards is still in excess of 3,000 fps. /ubbthreads/images/graemlins/shocked.gif
Energy in foot-pounds generated at the muzzle is 3,660, and at 500 yards, it still maintains 2,057 foot-pounds of energy, plenty enough for any whitetail!
This almost sounds too good to be true, but it is interesting food for thought. Anyone ever had one of these or known anything about them? Can it really be loaded this hot without excessive pressures? Sure hate to spend the money only to find out that it was mostly hype. I'm sure this wouldn't be really "fur friendly" /ubbthreads/images/graemlins/smile.gif
