Haven't used the TBT or TLR, but the Trophy Bonded Bear Claw is a great bullet for bear and elk.
If you have a chronograph, I'd use it when firing those various factory ammo to give you a feel for velocities. I've chrono'd alot of factory ammo across multiple lots per supplier as I had some custom turrets made for my scopes (this was before I started reloading). In my experience, Nosler factory ammo is closest to their stated specs, whereas others are consistenlty slower than their stated specs (I've seen some ammo suppliers almost 200fps slower than claimed....HSM being the worst that I tested, although DoubleTap also had some inconsistencies).
