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.

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.
