Which weight bullet would you prefer shooting Whitetails from a 7mm Rem Mag at 300-400 yards? Also, would you prefer the Ballistic Tip or Accu-Bond? I'm leaning towards the 150 gr thinking that maybe the wind wouldn't effect it as much as a 140 gr. But, the 150 is going to drop more due to it being heavier and will be traveling slower on impact. I've just acquired a Gen 1 Remington Sendero in 7mm Rem Mag with a 26" barrel and want to work up a load for it. I want to start trying some 300-400 yard shots on deer because we have power lines and huge clear cuts on some of our properties. I regularly kill them out to 200 with another 7mm mag I have (24" barrel) using 150 grain Ballistic Tips on top of 62.5 grs of IMR-4350, muzzle velocity is 2950. Any advice or recommendations would be appreciated.
