Partitions are great, I can't say anything negative about them when it concerns big, big game such as elk. But I would also consider the Speer Hot Core, they are considerably less expensive too. I have taken numerous large game, including elk using a .270 win. 130 gr. Hot Core's. Currently, I am running the 145 gr, in 7 mag. and it has performed just stellar on tough shoulder shots.
Another good bullet for elk sized game is the Speer Grand Slam. I've used them before, but they lack a little bit of B.C., which is kind of important to me since many shots are at rather extended distances in my neck of the woods. This makes BDC applications harder to calculate and to correlate with my Leupold RF w/ TBR and the reticle configuration. No biggie, just easier to use a bullet with a more typical ballistic characteristic in this respect for me. But at distances of 250 yds. or less, it really doesn't make much difference.
BTW, a long time buddy of mine recently took a 333" bull in S.W. Colorado using the 145 gr. Hot Core also.
