HSM Ammunition Starline Rifle Brass Unprimed Cases 6.5 Creedmoor Caliber 50 Per Bag. 5 Creedmoor Rifle Brass 50 Per - The 6.5 Creedmoor was designed as a target caliber in 2007 by Hornady but has become an extremely popular hunting caliber as well. While it isn't as long as some of the other 6.5 caliber short action calibers such as the .260 Remington the Creedmoor utilizes a 30 degree shoulder and very little body taper to help it achieve similar ballistics. The shorter length also gives it more versatility as far as bullet seating depth is concerned. Almost every major rifle company offers either a bolt-action rifle or a modern sporting rifle in the 6.5 Creedmoor due to its versatility and inherent accuracy.
