Looking for some advice on ammo/bullet selection in 300 Rem. SAUM for an upcoming elk hunt. Ammo is tough to come by though I'm looking at Rem Premiere 150 & 165 Core-Lokts; 180 Premiere Core-Lokt Ultra Bonded; and Nosler Customs in 180 partitions. I don't handload. The Remington 165 and 180 shoot well in my gun. Haven't shot the Remington 150 and Nosler 180.
Also, all things being equal, how much better is this caliber over the 30-06 or 308 for elk?
