I have a wide range of calibers, so I don’t need to go outside of what I consider the normal band of bullet weights for caliber.
Unless I was a diehard .270 fan, I don’t see the need to shoot 175 grain bullets from a .270. I have 7mm and .30 cal rifles for that.
I guess this is the long range option for .270 fans and is meant to complete with the long range 6.5mm cartridges (6.5 Creedmoor, 6.5 PRC, etc...).
