I just checked my collection of bullets I got from Dale/Chinchaga Bullet Co, and he does/did make them.
I am not sure if he still has the forming dies, but he did have them. We made a few different bullets when I was there one time.
From left to right: .257 caliber,135 grain ULD, .308 caliber, 155 grain ULD, 235 grain ULD, .338caliber, 300 grain ULD
(ULD= Ultra Low Drag)
