I'd try the Sierra 120 grain spitzer, the Hornady SST or Interlock or the Nosler BT. The Partition is the bullet that all others are compared to; if you need a Partition, chances are good that you need a bigger bore. If it stomps, gores, scratches or bites, use the PT. For whitetails, I'm sold on the Sierra or Hornady. Last year an aquaintance shot 8 deer with 8 shots, only one took more than 2 steps. Bullet? 139 grain Interlock BTSP 7mm caliber out of a 7mm/08 over H414. Try the 120 in your 260; I think you'll do just fine.
If you want your children to follow in your footsteps, be careful where you walk.
Beware the man that only owns one gun; he probably knows how to use it.
I just hope my ship comes in before my dock rots.
