I agree the published data really means squat on factory ammo, unless you chrono the loads your only guessing that the factory ballistics are in fact exhibited in your rifle. The only way to know if a certain ammo is accurate and fits your needs is to shoot it, paper comparison are only a starting point and to shoot .6 at 100 is great but what happens at 350. All I am saying is whatever ammo you choose make sure you shoot it all intended ranges so you know what to expect when an animal appears in the crosshairs. If you have no access to shoot 350 yard in practice IMHO you have no biz shooting this distance in the field.

As to the light mag ammo by Hornady it depends on the rifle, best option is pick up a box and give her a go. The Interbond should be a good choice if your gun likes it. Some other bonded/boattails would be the Barnes Triple Shock or Nosler Accubond which are both loaded in the federal premium line. I also believe winchester supreme is loading the Nosler Accubond in come calibers this year as well. If deer hunting you could look at the Nosler Solid Based BT or Game King BT in Federal Premium line as possibilities, however if your a pin aimer then I would stick to a bonded or Nosler Partition.
