Hello my name is Chad, I am a deployed soldier looking to get started in longe range. I have a rem 700 sps in .300 wsm with a leupold 4.5-14x50 vx-3. Looking to shoot no further than 500 yards. Hunting Oklahoma whitetail. Will this equipment get the job done and what kind of factory ammo would you reccomend. Also looking at replacing trigger. Was looking at the timney and the jewell. Any thoughts?
