Can't go wrong with nosler - Nosler Trophy Grade .300 Winchester Magnum 180 Grain AccuBond Brass Cased Centerfire Rifle Ammunition

Bought 2 boxes of these last year for an otc colorado elk hunt. 3 round groups on paper with my Remington 700 at 200 yards were the size of a quarter which is far better than every other factory ammo ive run through the rifle. Shot a bull through both lungs at 350yrds on our last day of the hunt and he went down within 50yrds of impact. Worth the money
