I have been through the load development process twice with my 30BR, using 125gr SMK and 125gr NBT, only to have the source dry up just when things got interesting.
So I posed the question of performance vs price and availability to my dealer, and he came back with the Sierra 125gr Pro Hunter. He suggested to me that this flat based soft pointed hunting bullet is a lot more accurate than its price and easier availability might suggest. He also told me that when rifle manufacturers include a representational target showing the individual rifle's accuracy, those targets are shot using Pro Hunters.
The Sierra .264" 120gr Pro Hunter #1720 might be a surprisingly useful alternative, at least at distances where flat based bullets are preferable. Also, Like Nosler Ballistic Tips, they could provide for a multi-purpose cartridge.
