The History Of The 6.5s

In the two cases, the cartridges have their beginning at Hornady, under the direction of David Emory. The organization’s previous senior ballistician shepherded both the 6.5 Creedmoor and the 6.5 PRC through improvement and to advertise. And keeping in mind that the objective of the cartridges is to some degree comparable, their beginnings are unique and add evenness to the 6.5 PRC versus 6.5 Creedmoor conversation.

As many have heard at this point, the Creedmoor was brought into the world from long-range shooting contests and back-of-the-envelope designing among Emory and champion shooter Dennis DeMille. A bull meeting over the inadequacies of long-range cartridges—a greater part of which were wildcats at that point—the pair worked through a rundown of the trademark for what might turn into the 6.5 Creedmoor. These included:

Great ballistic coefficient to buck wind and drag

Convey higher speed than other 6mm and 6.5 rounds

Low chamber strain to broaden case and barrel life

Low backlash

Simple to reload

Fit in an AR-10 and short-manual action

While numerous shooters use the 6.5 Creedmoor for more than ringing steel—it’s an amazing medium game cartridge—its introduction to the world came to fruition through contest. For the 6.5 PRC, match gold was just a large portion of the point.

George Gardner, proprietor of GA Precision, had a double reason as a main priority with the supersized 6.5—hunting and Precision Rifle Series contest. A difficult one to figure out, given the two pursuits are at chances by certain records. Especially with regards to PRS rules, which direct endorsed cartridges can’t have gag speeds surpassing 3,200 fps. To this, he needed the most elevated ballistic coefficient (BC) slugs viable with the cartridge. Moreover, Gardner additionally wanted a cartridge viable with a short-activity beneficiary—every one of the more effective in aggressive circumstances. Later a concise redirection—because of metal deficiencies—into the 6.5 SAUM (Short Action Ultra Magnum), the idea happened as expected in the 6.5 PRC.

Creedmoor And PRC Performance

Not miles away, but rather unique enough, the improvement boundaries for the cartridges characterize the 6.5 PRC versus 6.5 Creedmoor discussion. Where the Creedmoor was a blending attempt for a reasonable cutthroat cartridge, the PRC was one pushing the redline without going over. In the two cases, actually quite difficult. Yet, hard to contend effectively cultivated on the two counts.

Three 6.5 Creedmoor manufacturing plant loads from Hornaday (left to right) 120-, 129-and 140-grain shots. Note the organization doesn’t clean out the staining from toughening.

Basically, the splitting trademark between the 6.5s is their cases. For the 6.5 Creedmoor, Emory and team went to the Hornady-grew, however to some degree dark .30 TC for the parent. What attracted them to it were some splendid layered attributes. Specifically, negligible body tighten and a 30-degree shoulder point gave imperative ability to the 1.920-inch case permitting it to situate the long 6.5mm projectiles to most extreme COL (cartridge by and large length), without uprooting powder.

Once more, Hornady examined house for a parent case for the 6.5 PRC—the .300 Ruger Compact Magnum. Giving the perfect harmony between the case-ability to arrive at the 3,200 fps mark at the gag and estimate to work faultlessly in a short activity, the case demonstrated ideal for the PRC project. As a side note, the PRC doesn’t fit the specialized meaning of a short-activity cartridge, with a greatest COL of 2.955. By the by, it works in the contracted activities.

The 6.5 PRC has particularly upgraded limit contrasted with the Creedmoor because of its parent case—around 28-percent—which amounts to greater speed—the 8-percent area. This adds up downrange. A speedy model may reveal some insight. Take Hornady’s 147-grain 6.5 Creedmoor and 6.5 PRC Match loads, finished off with indistinguishable projectiles (Extra Low Drag Match), with indistinguishable BCs (.697 G1). The PRC pushes its shot from the gag of a 24-inch barrel at 2,910 fps contrasted with the Creedmoor’s 2,695 fps. That is a distinction of 215 fps, at 1,000 yards this implies around 50-inches less drop and push the imprint at which the slug goes sub-sonic by another 250 or so yards.
