Shooting and Loading the Hornady 6.5 Creedmoor

The debut of a new target cartridge is a rare event. In 2008, Hornady Mfg. Co. added the 6.5 Creedmoor to that select group.


While new ammunition offerings for hunting come out just about every year, the debut of a new target cartridge is a rare event. Only a handful of factory competition rounds-such as the 6 mm PPC, 6.5x47 mm Norma, DTAC 6XC and 6.5-284 Win.-have been introduced in the past couple of decades. In 2008, Hornady Mfg. Co. added a new cartridge, the 6.5 Creedmoor, to that select group.

The 6.5 Creedmoor resulted from a conversation in 2007 at Camp Perry between Hornady Senior Ballistician Dave Emary and Dennis DeMille, general manager of Creedmoor Sports and 2005 NRA National High Power Champion, about the ideal match cartridge. DeMille suggested a list of characteristics, including match-grade accuracy, a high-ballistic coefficient (BC) bullet, low recoil, good barrel and brass life, moderate chamber pressure, wide availability, affordable and a 2.800-inch overall length for feeding from short-action magazines. Emary took DeMille's list back to Hornady and used it to begin development of a new cartridge.

Emary selected 6.5 mm for the new round because of the available selection of 0.264-inch-diameter match projectiles, all of which offer high ballistic coefficients and excellent accuracy. It also didn't hurt that one of the very best of those projectiles-the 140-gr. A-MAX (0.550 BC)-was already made by Hornady.

The new cartridge, named 6.5 Creedmoor in recognition of DeMille's contribution, commenced production in June 2008 with Hornady's new 120-gr. A-MAX bullet (0.465 BC). The 140-gr. A-MAX load was released in volume about a month later.

The 6.5 Creedmoor could be described as a .260 Rem. modified with a 0.11-inch shorter case, a sharper 30-degree shoulder, and less body taper. Full case capacity of the Creedmoor is 52.1 grs. of water, compared to 54.4 grs. for the .260 Rem. (both measurements taken using new, unfired cases). When match bullets are seated to 2.800-inch overall length (OAL) in both cartridges, however, the deeper bullet intrusion into the Remington case reduces the difference in effective capacity to only about 0.7 gr.

Current specifications for the 120-gr. A-MAX load are 44.5 grs. of H4350 powder, a Fed. 210M primer and 2.720-inch OAL for 3020 f.p.s. muzzle velocity. For the 140-gr. A-MAX, they are 41.9 grs. of H4350, a Fed. 210M primer and 2.80-inch OAL for a muzzle velocity of 2820 f.p.s. Velocities were measured in 28-inch barrels. The OAL of the 120-gr. load is shorter than that of its 140-gr. sibling to accommodate the lighter bullet's fatter ogive, which requires deeper seating in the case to prevent contact with the rifling.

Reamers for the cartridge are made for Hornady by Pacific Tool & Gauge. By standardizing chamber and throat dimensions, Hornady can produce factory 6.5 Creedmoor ammunition capable of consistent performance in any rifle chambered for it....

Big deal. They reinvented the 6.5x55 Mauser but shorter.

Just purchased a Ruger Mark II Target rifle. On the breaking in of the rifle had around a .5 inch at 200 and under 3 inch group at 650 yards with the factory 120 grain amax loads can't wait to get to the range with the130 grain VLD pills after breaking it in.

I have a creedmoor and I love it, whether it's long range hunting for deer or just banging jugs and clay pigeons with the boys it is awesome.... I shot a 3.25' group @ 785 and have no problem dialing up jugs at 900+ I would recommend this cartridge to anyone looking for a great long range gun!!

I have recently bought a savage model 12 lrp in the 6.5 creedmoore. I got it for my new competition rifle but the factory 140 amax did a decent group with winds varying from 15 to 25 mph at 600 yards measured just over four inches not a bad round at all

I dont know much about long range shooting,but I think a6.5x55 in anew 26in rifle would do better than what you have listed. Iget 2580fps out of a midel 96 swedish mauser with a160 round nose 22in barrel using Lee reloading data
