I would say it depends on what twist you're shooting. For a 10 twist bbl, it is hard to beat the 87 grainers. you can get them smoking out of an ackley case, almost up to 257 weatherby standards. For some faster twists, try the 115 Bergers. There is a very noticeable difference in "umphh" that the 115's carry over the 107's.
I have shot a couple deer with the 107's out of my ackley, and I wasn't that impressed, they both pencilled through and needed a follow up shot. One was at 680 yds, and the other at 710. I was pushing them at about 3100.
As far as the 115's, just have one kill, (508 yd deer), high shoulder shot and she never knew what hit her.
