As far as I know is that 338 Tomahawk is based on 300 ULTRA RUM, blown out the shoulder (a little wider and 35 deg)and necked up to .338 cal.

I'm not sure what to call it for 338 Ultra Imp. (Perhaps call it 338 Edge). This brass is a little shorter than 300 Ultra RUM. If you are looking for more capacity of powder, go for 300 RUM brass or 375 brass and neck down to 338.

Does this make sense to you?

Yes the 338 Tomahawk exists and does quite well. Ray Romain has this reamer and it is based on the 300 Tomahawk case. I form mine from 375 ultra mag brass.

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
