I have one on order with Preferred Barrels. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 7mm Remington Magnum ~ 150 Grain ~ Trajectory Chart. At 1000 yards the rotation of the earth is basically moving your target down 2.6 inches per second if you are pointing east, and up if you are pointing west. Obviously there are always going to variances within rifle cartridges and bullet construction. Not being a downer on innovation, but 7mm STW is made by a lot more manufacturers than I see 7mm PRiCey ever being made by. I ABSOLUTELY would use 7mm PRC on elk. In other words what barrel length will produce a 3,000 fps muzzle velocity using the factory loaded Precision Hunter 175 gr ELD-X bullet? ballistics software below for the same load: At 500 yards the remaining velocity is 2264fps again, this is exceptional ballistics for a bullet weight in this class and diameter. I used the same primer, and the same 175gr ELDX bullet. What are the speeds youre getting with your 20 barrel? Lol. I was somewhat surprised by the list of firearms manufacturers who are not yet jumping on board with the 7 PRC. Thats what Im really most curious to know. Think of it as a modernized 7mm Rem Mag. 375" drop w/ 100 yard zero. Ill keep you posted! on steroids. I think all the powders you have tried except H4831SC are too slow. Its a direct thread. Let's compare the amount of wind deflection for two different bullet's launched at 3000 fps MV. And shoot 168 Barnes tipped triple shock bullets along with Berger VLD at same weight and load. The Extreme Spread (ES) of our velocity is usually under 10 fps and Standard Deviations (SD) is usually around 3-5 fps. Again, BC and velocity is important. Ive done a significant amount of handloading and reloading for the 7 PRC over the last few months. The challenge of loading for any of the PRC cartridges is the extremely tight tolerances. I use a Griffin ultra-light 30 cal suppressor and in all of my rifles I average around a 60 FPS velosity gain over a brake. Im not talking about self-doubt or simply asking yourself what if I miss. Be cautious when rebarreling a rifle into any of the PRC cartridges. Hopefully with its introduction it will make SAUM brass easier to find because more people will go for the PRC moving forward. How will that compare? 7mm Ballistics Examined For this ballistics demonstration we are using Norma 150gr Scirocco with a muzzle velocity of 3117fps and a ballistic coefficient of 0.536. However, its pointless to attempt such shots if you dont optimize 7mm Rem Mags point blank range during sighting-in. We analyzed 6 different loads for each cartridge (the proper way to read that sentence is Jim sat at a computer for WEEKS putting data into very complicated Excel sheets) to come out with an average of what several common loads for each cartridge will accomplish. They use Berger 168 gr VLD (Very Low Drag) bullets. Our reference system will take 1.3 seconds to reach 1000 yards. Max range 600yard, would like to shoot the 180s. We carefully monitor the velocity until we see a significant increase (30-60 fps) which usually takes around 40 to 60 rounds. The higher the number, the better down range velocity retention. Cartridge Type: RifleHeight: 2.5"Width: 0.532"Average FPS: 3024Average Energy: 3106Average Gr: 153Recoil: 2.06Power Rank: 4.63 of 20. I was about to embark on a 7 Saum build in a long action to use the longer, higher BC bullets. But, everything has to be perfect for it to work. Initially, I expected H1000 or Retumbo to be the best powders for the 7 PRC since they are fan favorites of the 7 Mag. I wanted to use a 20 barrel suppressed on my 7mm PRC. All Rights Reserved. In certain situations we may suggest the use of ballistic turrets and for most scope models we can have custom turrets cut according to your load data. External ballistics covers everything that happens during a bullet's flight between the muzzle of the rifle, and the target. Very well done. The 7mm PRC is a new round designed for long-range shooting and big-game hunting. Im a big fan of the channel and look forward to more on the 7mm PRC. You might be able to measure with a data meter the speed and direction at your location, but the wind is very likely doing something entirely different at mid-range, or at the target. While we have went to great lengths to make sure that it's as accurate as possible this rendering should not be used to generate specs for casings. The data in the following table contains averages for each cartridge. Interestingly, I loaded 61.2 grains of H4831SC in a 7mm Remington Magnum, and a 7mm PRC. This round is here to stay, and while the relative recoil or kick is often sighted as negative, it's often over stated, while it does kick the numbers show that the recoil on average is = or less than the average for the 30-06 but is of course more than the 270, and the 30-30. Its currently in a google sheet so I can easily share access with a good email. Again we see how important a short time of flight is to minimize these effects. Rifle Type Both the 7mm Rem Mag and the .300 Win Mag are only chambered in standard/long action rifles. Im not sure that muzzle velocity would have helped this discussion, though. Or, you can of course use a custom action like a Terminus, Defiance, etc. Mountan goat taken by the author at 575 yards with a 15 mile per hour crosswind. If its a can that takes a threaded muzzle device or a QD mount then who installed the device and did you time it for minimal POI shift? Depending on bullet type and construction, the minimum expansion velocity for rifles falls between about 1300 and 2000 fps. For instance 180 grain bullet out of a .30-06 will have a range of numbers even if the MV is the same, as you can have bullets like VLD, spitzer/hollow point boat tail, flat base, and round nose bullets all found in factory loads. Still havent been able to find brass. But these eyes have seen better days (literally). Well done mate , wont 7wsm do the same?? Note that with these loads, I switch to a standard large rifle primernot a magnum primer. The 7 PRC is designed around the 180-grain ELD-Match bullet; however, some people will certainly point to the fact that the 7mm Rem Mag has been able to shoot 180-grain bullets for many decades. The recoil of the 7mm PRC produces 27.7 ft-lbs of energy at a recoil velocity of 14.1 fps. The 7mm Rem Mag is another specialized cartridge that deserves comprehensive ballistics analysis using Shoot! Your email address will not be published. Thats a dead whitetail deer out to 1200 yards lol. Im running a 20 tube on a Bergara action. There are 100s of different 7mm Rem Mag factory ammunition loads and bullets to choose from in Shoot! Im still using the same 24 test barrel by Preferred Barrel Blanks for this cartridge. These guys have 7mm rem mags taking elk at 900+ yards. Load Swift's 150-grain Scirocco at 3,036 fps delivers outstanding terminal performance. Ballistic Profile Specifications: Scope height, velocity, twist rate, and all ballistic data to include bullet Ballistic Coefficient (BC), powder charge, Base to Ogive, and Cartridge Overall Length will be provided with the package. The bullet with the lowest expansion threshold is Nosler Accubond Long Range, which expands starting at 1300 fps. So far, my favorite powder for reloading the 7 PRC is H4831SC using standard large rifle primers. I have a table showing the highest BC 7mm bullets, but here are a few bullets likely to be popular in the 7mm PRC: Below are the specified twist rates for many similar cartridges to the 7 PRC. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. But with a TBAC 7 ultra on a Fierce CT rival. Maybe one day you could get a donor barrel from a sponsor, and cut it down in the field (no recrown) every inch from 28 down to 18 to see what all the velocities are? Ive got it sending the 162 grain ELD-X 3200 FPS. Just wondering. L. Neil Smith, at a 200 yard zero with a Hornady SST 162 gr your looking at 34.8" drop @ 500 beyond that it really really falls off quickly after that range . Loris: 50 inch would be uncommonly long. Unfortunately, as hunters we have other limitations that force us to settle for equipment with lower BC values and muzzle velocities. This can be useful in comparing cartridges or loads. Thats exactly what the 7PRC is, but it is by no means the only cartridge that offers those specs. Now, I either need to find ammunition to shoot, or new brass. Jim, I enjoy that you use your platform to provide reliable data to ethically take animals. N560 offers some of the best velocities without a compressed load. Starline Brass has plans to produce these cases in the future. It's like these other guys said, if you throw a small rock it goes really fast, but not very far. It was an exciting huntwe would spot goats from the valley floor, and climb 3000-4000 feet every day to hunt them. Haha your fan from Algeria. Youtube is full of those videos. 2023 Backfire LLC, a limited liability company headquartered in Utah, USA. Because the 7mm shoots the lighter bullets at higher velocities, it is better suited to the law enforcment arena than the .300. since Im a fan of your youtubes, my question to you: With the ammo and reloading components markets starting to normalize, when do you think 7mm PRC ammo and reloading components will be available this year?

Given a 10mph wind and an average load, it drifts just 0.3 at 100 yards, 14.5 at 500 yards, and 69 at 1,000 yards. Eliminating the effect of wind by using high BC's and proper compensation techniques is the only solution. Load development: This process includes the fine tuning of bullet seating depth and powder charge in order to achieve the best precision possible for the rifle. The Fora platform includes forum software by XenForo. A bullet traveling through the air will lose velocity, and the bullet's shape effects how fast it will slow down. Does anyone know how hot you can load a 162 gr. Did you perhaps mean 50 cm? Here are the ranges for a 190gr A-Tip Match in a 27in 7.21 Firebird at 3240fps: 1900fps: 1250yd The bullets BC (ballistic coefficient) is very high at 0.536. Couple questions for you. Required fields are marked *. The 7mm PRC is similar to a 7mm Rem Mag, but it can shoot heavier bullets with higher BCs, has no belt which causes problems for reloaders, and slightly less case capacity so longer barrels are not necessary.

Seriously, its by far the nicest die set Ive ever ownedand Ive tried just about every brand out there. The aim ballistically for Hornady with the 7mm PRC, is for a cartridge that will fire a 180gr 7mm bullet at around 2950 to 3000fps. What is the mounting method, QD or threaded? Use a small level, and look closely at new rangefinders that incorporate incline shooting compensation. Sighting-in a hunting rifle to hit a certain number of inches high at 100 yards (or 100 meters) maximizes the point blank range of the rifle and cartridge and is superior to zeroing at a fixed distance like 200 yards. It produces 1,500 ft-lbs of energy for elk-sized game out to 510 yards, and 1,000 ft-lbs for deer-sized game to 810 yards. For this experiment, well look at three common ways to determine effectiveness. 7mm Remington Magnum Despite its age, the 7mm Rem Mag's ballistics perform well even by today's standards. I'd throw a link in, but i don't know how from an iPhone. In fact, Aaron Davidson, CEO of Gunwerks, jokingly said that the new 7PRC is the 7LRM. In the past too much attention was placed on increasing MV, but modern long range shooters realize that increasing the BC increases performance without increasing recoil. You want to take full advantage of this cartridges ballistic potential. However, why was the 8mm Mauser left out of this comparison?
