300RUM. 180gr Nosler Accubond.
375 H&H. 300gr Barnes TSX.

Barnes TSX in the rifles with higher muzzle velocity; they're accurate and perform well on game.

Nosler Partition on those occasions when a short magazine/action doesn't lend itself to the longer TSX (example: .350 Remington).

Hornaday in the old, slow whitetail "brush" calibers.

Have found that what works in one gun isn't always the best for another caliber, accuracy wise that is. I Like premium bullets, but the Game Kings and Core Lokt are pretty nice to have in the lighter rounds for pigs coyotes and paper.

Swift A Frames in 450 & 470
Nosler Partitions in '06 & 7mag
Game Kings in .308 & 223
Core Lokt in 7.62x39
Grand Slams for 7mag

If it was just one bullet - Barnes TTSX they don't mind heavy bones in the way of the vitals and anchor big game well. But for deer the Nosler BT is hard to beat. You do need to keep a close watch on your deer with them so you can remember where they were standing when they died.

Barnes tsx and Sledgehammer solids in 9.3x62

200 and 250 gn round nose in the 35 WHELEN

In my Remington 700 3006 cal 165 Barnes TSX in Remington 700 in 270 cal 150 flat base Barnes TSX great on all North American game and a lot that Africa has to offer

Barnes TTSX or any Barnes X bullet.

My favorite bullet is one that lands in the right place.

I have used Hornady Interlocks, Interbonds, & GMX's. Nosler BT's & Partitions. Barnes X, TSX & TTSX. Swift A-frames. Trophy Bonded Bear Claws.

I suppose if I had to pick one, it would be a monometal. Specifically a TTSX as it comes in more weights than the GMX.
