Do yourself and the deer a favor. Forget the Bergers and go with proven bullets. Sierras are fantastic. Really like the 120 Gameking. The Nosler 110 Accubond kills deer as well as any bullet I have ever shot. 2 years ago I lost 2 bucks shooting Bergers out of a 270. One of them was a wallhanger. No penetration.
I will be able to tell you in November how they do. I'm shooting them out of a 25-06 going 3135 fps. I'm hoping to drop some whitetail where they stand with them. On the other hand I've had several deer drop to both the 100 grain GK and the 117 GK. I expect extreme internal damage with the 115 grain bergers at close range, but that's ok with me when I'm only dropping 28" to 500yds.
Last year's production:
100gk's don't fare well on front on chest shots, (heart turned inside out, deer dead very quickly. no exit but dead deer still the same) GK's and MK's work well on ground hogs just no spectacular effects like true varmint bullets.
117 gk's exited after mutilating both lungs and breaking offside shoulder (deer dropped in tracks; nice entrance and exit)
The Berger has been looking good in our 250AI in the 3000+fps range but in the ranges your taking just about any bullet you stick in it will tip deer, also like the 120 Hornady interlock and it's done a nice job on the past few elk it's been used on. I've tried seriously for five years to get a Berger to blow up, all I've had is piles of dead game and a 100% recovery rate, even tried 140's at 3300 fps from my 270 WSM and 60gr from a 22-250 at 3500fps and no dice, they just fall on their nose
