Kind of curious about this cartridge. I have an Win 70 Classic magnum action that needs a makeover. I am covered on the larger calibers. About my only gap is something that shoots really flat. A 270Win using 130gr at 3100fps is as fast/flat as I get right now. Any weaknesses, hard to get good loads, etc? Is brass a PITA to find? I only reload so factory ammo is not an issue.
