Off the top of my head, almost certainly forgetting some, various yardages, various cartridges (243, 270, 30-30, 300 Sav, 308, 30-06, 300 WSM).

165gr GMX
165gr Core-Lokt
180gr Core-Lokt
180gr Interlock
180gr TTSX
180gr Federal Trophy Copper (whatever bullet that is)
General notes: Heavier bullets that hold together consistently get more penetration than cup and core bullets and therefore kill more consistently. I've seen cup and core bullets fail a whole lot of times. Of course this doesn't always mean a lost animal, you can make an elk die with anything, especially if you hit them anywhere near where you are aiming, and you are aiming in a good spot. Light for caliber Sierra Gamekings have got to be the worst I've seen and I think Core-Lokts are the best cup and core bullets.
Elk aren't bulletproof, they are just big, and you can't get too much penetration. Bonded and monolithic bullets just do such a better job, consistently. Still never used a Partition but they should work great for the same reasons.
