Most of your modern 1-28 twists are made to shoot sabots. Whether they shoot a conical or a powerbelt is something only the rifle knows. The BPI rifles do seem to shoot Powerbelts well, but of course they have a stake in the powerbelt sales as well.

When I look for a "conical shooter" I used to always look for the 1-32 twist rifles. Why the White rifle shoots conicals in so perfect a manner, has to be a very careful design of the rifle, twist, and rifling depth.

I've never played with an Omega and conicals, but I would guess that there is a conical out there that they would shoot very well. My Knight Wolverinefor instance does real good with the 250 grainSaber Tooth as does the Black Diamond XR. My CVA shoots Powerbelts. And my Black Diamond XR shoots No Excuse Conicals very well. But all of that took a lot of range time and testing to find these different loads.
