you're welcome. On the 50-110 brass I first went

with the 50 Alaskan sizer die to size the case, then went with the 476 GNR sizer die, then the 450 GNR sizer die and finally to the 416 GNR sizer die. The neck on the cartridge will be .300. A bit longer but Dave Manson said we needed it over the .250 I wanted. The new 417 GNR holds 20% more powder than the older 416 GNR in total case capacity so I would think we should be able to gain 150 fps or maybe a bit more in a 16" barrel. Reamer is on the way and your barrel will be shortly behind that.
