7 PRC vs 7mm Rem Mag: Here’s Why the New Cartridge Is Superior

The 7mm PRC made quite a splash when it was introduced by Hornady just four years ago, with some calling it the “modern magnum” of 7mm cartridges. That’s because it embodies the same modern cartridge design principles used in rounds like the 6.5 Creedmoor, 6.5 PRC, and 300 PRC. In some ways, it outshines all of these, and delivers more efficient performance than the 7mm Rem. Mag. It does so from a standard-length action without using a belted case.
Based on a shortened .375 Ruger parent case, the 7mm PRC uses long, heavy-for-caliber bullets in rifles with fast rates of twist (most often 1:8). As a result, it shoots flat, bucks the wind, retains velocity downrange and is inherently accurate. Using Hornady’s 175-gr. ELD-X bullet, the round stays supersonic past 1,800 yards, and energy doesn’t drop below 1,000 foot-pounds until nearly 1,200 yards. That’s overkill for the whitetail woods, but it makes the cartridge a great choice for Western hunters pursuing mule deer and elk at longer ranges. It is also very much at home on the African plains.
Rifles chambered in 7mm PRC generally produce great accuracy — especially when compared to some of the traditional magnum cartridges. PRC stands for Precision Rifle Cartridge, and the entire family of PRC cartridges was designed from the beginning to produce superior accuracy at distance.
The 7mm Rem Mag was not. It was designed to perform well on game at a time when 1.5-MOA accuracy was considered very good for factory rifles using factory ammunition. This isn’t to say that the 7mm Rem Mag is an inaccurate cartridge. Over the years, my average 3-shot groups with most 7mm Rem Mag rifles were fairly close to one MOA, or a little better with loads those rifles preferred — a few guns occasionally did better. This, of course, is just my anecdotal experiences shooting the cartridge, not the end-all-be-all commentary on its accuracy.
The rifles I’ve shot in 7mm PRC have seldom failed to print 3/4-MOA-or-better average groups and half-inch-or-better best groups at 100 yards (these were 3-shot groups, again take this as anecdotal evidence).
I think this all depends on the weight of the gun and the ammunition you shoot. Frankly, I don’t really like the Hornady ammunition. In my 7mm PRC rifle I find that Nosler does better.
You will often hear that the 7mm Rem Mag produces more recoil than the 7mm PRC, but that’s not necessarily the case. Yes, the 7mm Rem Mag can produce a punishing level of recoil, especially out of lighter rifles with heavier loads. However, many hunters commonly shoot 7mm Rem Mag ammo loaded with lighter 140- to 160-gr. bullets, which can produce less recoil than shooting the 7mm PRC’s heavier standard bullets.
Those fast, light loads came in handy at a time when hunters were mostly using the holdover method for longer shots (before laser rangefinders were invented). Part of the 7mm Rem Mag’s appeal, especially with Western hunters, was that it shot relatively flat.
On average, the 7mm Rem Mag produces about 22-25 ft-lbs. of recoil energy, while the 7mm PRC produces average recoil energy of approximately 25-29 ft-lbs. However, those average numbers can be misleading because recoil energy varies greatly depending on factors like rifle weight, bullet weight, and powder charge.
With heavy rifles, recoil with both the 7mm Rem Mag and 7mm PRC is manageable for most shooters. Drop the rifle weight down, and recoil can become a problem for either cartridge.
You need a muzzle brake. At one time in my shooting career, I would have considered this amount of recoil to be punishing. That was true up until I shot the 444 Marlin, which honestly isn’t so punishing either when you’re hunting. It’s quite manageable — right up until you’ve shot 15 or so rounds bench rest. And then I begin to look for opportunities to rest and regroup between shots. There is no point to shooting that many rounds of 444 Marlin anyway. Sight it in and be done. It’s a hunting round.
As I’ve mentioned, I am profoundly impressed with the 7mm PRC.

Both cartridges are more capable than 99% of the people that shoot them. The same is true of most modern rifle cartridges.

The team at Hornady have created the 7mm PRC out of a few narrow gaps which existed in the well-established 7mm Remington Magnum design, which officially came out in 1962.
First, although the 7mm RM case is a magnum, much of its interior volume is lost due to the need to seat bullets far-enough into the case to have the desired neck tension on the bullet and proper presentation of the bullet to the throat of the barrel.
According to Hornady, the larger diameter 7mm PRC case body, its slightly shorter case length and steeper shoulder all combine to allow a larger usable volume for propellant, allowing performance – they claim – matches or exceeds that of 7mm Rem-Mag.
“Claimed” is in parenthesis because not everyone is agreeing with Hornady’s claim; i.e., the skeptics believe that 7mm RM still holds more powder than the 7mm PRC.
The design of the 7mm PRC case neck allows long/heavy-for-caliber high-BC projectiles to be used with the cartridge, something which the company claims is not always possible with 7mm RM.
The second window of opportunity for 7mm PRC comes in the fact that rifles in 7mm Rem-Mag are typical released with 1:9 or 1:9.5 RHT barrels, a rate of twist which is often too slow to stabilize the most-modern high-BC projectiles used for hunting and LR competition.
Hornady has taken the care to cooperate with a number of rifle manufacturers to assure that their new rifles in 7mm PRC have the necessary faster twist rates needed for the new 7mm PRC; these include Savage Arms, Ruger, Browning, and some others. There are also a few companies that are sticking with 1:9.5 twist barrels.
I have been a fan of 7mm Rem-Mag for a long time, and own an exceptionally accurate well-made rifle in that chambering. My sole complaint with it being the too-slow 1:9.5 twist rate.
At least in my case, that is what made the 7mm PRC attractive. It isn’t the 7mm Rem-Mag itself with which I have issues, it is the barrel twist rate on the rifle.
It turns out that getting a traditional medium weight, medium contour replacement hunting barrel in a blued finish and with the faster twist rate, is neither easy nor cheap. That’s where the 7mm PRC comes in….
As far as the geometry of the new cartridge case is concerned, I prefer the shape of the 7mm Rem-Mag to the modern, steep-shouldered appearance and form of the 7mm PRC. I believe – but cannot prove – that the older cartridge chambers and extracts more easily and more reliably, because of its gentler shoulder angle.
But as far as its performance is concerned, the new kid on the block delivers the goods. An acquaintance of mine who is not even an experienced long-range shooter, recently told me that he had made multiple hits on a steel gong at one mile using his 7mm PRC and one of those high-BC loads that now exist for the cartridge.

And I think I mentioned that I put a 7mm PRC round on IPSC steel at 1000 yards.

@ Herschel Smith
Yes, you did mention it, and good shooting! A grand is a long way off and even if the cartridge and rifle are top-notch, the man behind the trigger still has to know his business. Which you obviously did!
