Bob,
Have pointed this out before, but Norma Oryx's seem to produce the same effects as Bitterroots, bpth the thump when they hit and the internal damage. It's easy to see why if you ever recover a bullet, since they expand very similarly.
The only two drawbacks to the Oryx are a mid-range ballistics coefficient (similar to the BBC) and a rather limited choice of diameters and weights--complicated by Norma's spotty importation and distribution in the U.S. On the other hand, they're usually very accurate and the price is very good. A lot of people don't realize this, since Oryx's come 100 to a box rather than 50 like most other premiums these days. I just checked the Midway website and 180 30's are $57.99/100.
