I just ordered a remington 5r in 300 win mag with a 26" barrel. I plan to hunt and shoot long range with it. What factory ammo would you recommend I shoot in it for both?
Every gun is different for what it will shoot, but try any PREMIUM factory ammo such as Winchester, Hornady or Federal. Also, I like the 180 plus grain bullet weights for the 300.
For a side note, consider doing this gun justice by eventually reloading your ammo. These guns are historically very accurate out of the box with the correct load.
