My family used the 180 grain TSX on moose and caribou for several years with good results. Last year I switched to the 168 grain TTSX and it hammered the caribou at around 60 yards. I have several box's of the 175 grain LRX bullets and will probably load them up for the Pre-64 Featherweight 30-06 with a 22" barrel and use the 168 TTSX bullets in my 20" barreled Husqvarna 30-06.
For now the powder is H4350 for the 168 TTSX, but I may look at Hunter for the 175 LRX bullet. I will see what the chrony says.
According to Barnes both bullets will open up at below 1,600 fps, so in the big scheme of things, either bullet should work fine on elk out to 500 yards if they are loaded to their velocity capabilities, but closer is better. I would let the rifle tell me what bullet to shoot.
The 150 grain does not interest me for Alaska and it would not interest me for long pokes at elk, moose or caribou.
