Re: .284 Long Range Build
The 270WSM with a 150 Berger will rival some of the big calibers down range. It's an uncanny caliber that seems to defy the odds of BC when shooting. I think the simplest answer is that it can push them hard and fast. For what ever reason the .277 caliber really does a number on game too. So I would suggest hand loading 150grn either with the Hornady SST or the Berger Hunting VLD.
If you are seeking a .284 and just want to change caliber, than I suggest the .284 Winchester with 168 Berger, 162 A-max, 160 Accubond, and 180 Berger's. My other suggestion is the simple yet satisfying 7mm Rem Mag. If you want to go hot, then jump up to the 7STW.
