[QUOTE="Black Diamond 408, post: 222073, member: 1563"] I talked with Mr. Henson yesterday, his new dies have a shorter baring surface along with a #13 secant (if memory serves me) the standard Corbin dies are #10, the new bullets will look more like a SMK for taper. With the longer baring surface of the first production it will be hard to get the same velocity with the 280's compared to a 300smk bullet. The big difference is not in total speed it is the high BC his bullets offer. SMK at 2800 is around the published .768, the 265 or 280 AT bullets will generally run in the high .8's to low .9's Ive tested several different runs of his first prototypes, my 338 barrel is not made for the long bullets, so the tests dont offer much than velocity and if a 11 twist barrel will stabilize them or not. I shot some good groups with the 265's, 3400fps was about tops in my rifle. the 280's dont like the 11 twist so i didn't go any farther on them. I'm waiting to see the 375 and 416 version of the same configuration. [/QUOTE]
