They look a lot like a SW but they are supposed to have a thinner jacket on the nose an interlock like some of Hornadys CF bullets and the 250gr is designed for the Bushmaster 450; I have seen some of the bullets that came out of wild hogs from the first batches released and they looked like a very good mushroom for about 1/2 to 2/3 of the length of the bullet. They are designed for 2200 to 2400 FPS from what I have been able to fined out so far with 120 gr BHI wont be far off 2200 fps.
Since nobody answerd I assume since they have not been out long that they have not been tried. So I am ordering a hundred will check them out. Lee
