This is again shooting the 175gr ELD-X bullet out of 24 test barrel with a large magnum CCI primer. For what its worth longest shot was 823 yards with my Leupold vx2 3-9 but that was eight years ago I had them make me a short 20 carbon fiber-wrapped barrel chambered in 7 PRC. But, if you arent able to get things perfectly lined up for just long enough to pull the trigger and follow through a smidge, let it go. I just completed my 7PRC build, and have started testing. Increasing the BC to 0.700 the drift is only half, at 20 inches! If you check Hornadys load data it shows N560 for every bullet except the 190. Personally, my load for the 175 ELD-X in the 7mm PRC will be 64gr of H4831SC, which should yield around 2,925fps. The recoil of the 7mm PRC produces 27.7 ft-lbs of energy at a recoil velocity of 14.1 fps. Will be suppressed at times, but in a effort to save weight on certain hunts will ditch the can(7 TBAC Ultra). while they work great at closer ranges, they will fail miserably if you want to push your shots out there. Unfortunately, the chronograph (Labradar) glitched out and didnt record all the velocities, but I did at least shoot the following two that were recorded. Thank you. We need more ethical hunters who wont chance wounding an animal. This information is provided to the shooter as well. Great job on all the information on the 7mm PRC. It is caused by the bullet aligning itself to the relative wind vector. Initially, I expected H1000 or Retumbo to be the best powders for the 7 PRC since they are fan favorites of the 7 Mag. You lose about 25fps per inch of barrel from 24 to 20 inches in using a 7mm PRC depending of course on your powder choice. .300 Weatherby Magnum, .300 Remington Short Action Ultra Magnum, .444 Marlin, .327 Federal Magnum, .500-465 Nitro Express, 7mm Winchester Short Magnum (WSM), 6.53mm (.257) Lazzeroni Scramjet, 9.3x74R, .307 Winchester, .375 Weatherby Magnum, .577 Nitro Express 3-Inch, .44 Remington Magnum (Rifle Data), .416 Dakota, 10mm Auto, .375 Winchester. Round before it becomes inefficent? Thanks! You think they will come out with a 7mm Western? Its all highly situational, but it matters. You can get a new barrel for your Ruger American, Tikka, Bergara, Savage, etc. Little things that you may never have noticed can make a shot fail if you are really pushing the limits. deciding between the 6.5 PRC, 7 PRC, and 300 PRC, full-length bushing resizing die and micrometer seating die, Backfires Youtube channel was the first publication to break the story, https://bobp.cip-bobp.org/uploads/tdcc/tab-i/tabical-en-page36.pdf. 2020 Sierra Bullets Nice build Jim. Thanks for all the helpful info on the 7PRC. Lol. "Gun control: The theory that a woman found dead in an alley, raped and strangled with her panty hose, is somehow morally superior to a woman explaining to police how her attacker got that fatal bullet wound." The 7mm RUM is identical to a high performance race engine in every sense. Can you tell me which suppressor you are using? We carefully monitor the velocity until we see a significant increase (30-60 fps) which usually takes around 40 to 60 rounds. By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. Factory Savage 7mm rem mag 1000 yard video. Practicing in these conditions can yeild valuable experience.I'm always learning about how to become a better shooter, and I still make mistakes. When it gets mailed to you, you screw it on and you have a 7 PRC! But, everything has to be perfect for it to work. You may be able to use a heavier bullet and achieve more energy or a longer range with more velocity.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'backfire_tv-box-4','ezslot_6',175,'0','0'])};__ez_fad_position('div-gpt-ad-backfire_tv-box-4-0'); Since were talking about max distances, Id like to clarify something here. After that velocity diminishes very quickly. Sounded like your load data charts for the 7mm PRC were all done with 24 test barrel. My prediction? 7mm Remington: SP: 203: 2447: 2330: 7mm Remington che velocit riesci ad avere? Guessing and sighter shots have no place in todays hunting ethic. 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. 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. If you want to max things out, you need a bullet that will expand at lower velocities. 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? 7 PRC is designed for shorter barrels. Agreed that Whidden Gunworks makes the best reloading dies available. Ok ya that makes sense. Thanks, Jake. 7mms in general produce such good ballistics like higher retained velocity, energy, etc because of the bullets made for this caliber. They show how a 7mm with a 168 Berger has more energy down range than a 30-378 weatherby with a Barnes. Again, BC and velocity is important. The effective range of a bullet can be measured in different ways because it depends on what the bullet needs to be effective at doing. Worked up load with 195 bergers. If I add to that a gusty 25 mph wind, Im not shooting past 200 yards. I think your numbers might be off. Thank you for your efforts and info on this. Input your hunting conditions to see the drop, drift, bullet trajectory, velocity, and energy in easy-to-read ballistics charts and graphs. What barrel length has Hornady created the 7mm PRC for? Part of that preparation is understanding, in simple terms, the external ballistics of a typical long range shot. The heavy-for-caliber VLD bullet's are the only readily available high BC bullet's that have been documented to ethically perform at long ranges on game animals, and the BC range on those bullet's ranges from 0.550 to 0.685. Let's compare the amount of wind deflection for two different bullet's launched at 3000 fps MV. They sent me their full-length bushing resizing die and micrometer seating die and Ive been amazed with the quality. Haha your fan from Algeria. I will likely switch to that bullet once it becomes available. Please keep the good stuff coming. 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. We will also provide a dummy round for you to take measurements if requested. Im not sure that muzzle velocity would have helped this discussion, though. Sample Trajectory showing the bullet path crossing the line of sight.Because gravity causes the bullet to drop, the longer a bullet takes to reach its target, the more time gravity will have to pull it towards the earth. Any idea on predicted velocities for it? There are no bullets below the 0.284 caliber with a ballistic coefficient higher than the 7mm. Thanks for all the research and compilation here, are you certain of the numbers here as in many cases your distance where bullet travels less than 1500 fps is shorter than that same calibres 1900 fps for example 6.5 PRC? Starline Brass has plans to produce these cases in the future. Surprisingly, the factory ammunition for the 160gr CX bullet offers the same 3,000fps muzzle velocity as the 175gr ELD-X bullet. But keep in mind she kicks more than the .308 and is harder on barrels, but is a nice compromise between the 308 and 300 Win Mag. I feel it will offer the best velocity in a shorter barrel. RCC brass is the only place that has it, but the prices are wild at $6 per piece. Snow. 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. I was finally able to connect on a billy at 575 yards, but with a quartering 15 mph wind. Keep in mind this is an approximation and although it is quite accurate it should never replace first-hand experience of shooting your specific firearm and ammunition to determine the bullet drop and windage at different ranges and conditions. Important Note: This is anecdotal testing. We can minimize the effects from Magnus and Corriolis for sub 1000 yard shooting by zeroing at a longer range like 800 yardswhile pointing north or south. But what are the flattest shooting rifle cartridges? same principal applies to bullets. Decreasing wind deflection is a very important part of precise long range shooting. Unfortunately, no. Here is my info: 3040 FPS, 160 accubond at .531 b/c, 50 degrees and 5000ft. Hopefully with its introduction it will make SAUM brass easier to find because more people will go for the PRC moving forward. They gave me a 22 inch 7MM barrel blank so thats what I used for my 7 PRC build. Youre right. George Holt. for a 6 inch vital zone (typical of a whitetail deer). Tikka, Browning, and Bergara are conspicuously missing from the list and yet they all chamber for the 6.5 PRC. This difference in bullet shape can be quantified, and the comparison simplified to one numberthe Ballistic Coefficient, or BC. I'd throw a link in, but i don't know how from an iPhone. This is more than adequate for taking down large game the size of elk at this distance, provided you use the right bullet to penetrate to reach the vitals and place the shot accurately. I used the same primer, and the same 175gr ELDX bullet. A forum community dedicated to all firearm owners and enthusiasts. Im sure people will certainly use the cartridge for many things. PBB will just thread the end in a typical 5/824 pattern and then youll use a direct thread suppressor like a Dead Air Nomad. Know how well you shoot in different conditions and trust your skills. He is a well-known entrepreneur, having started many successful online brands, and lives in St George, Utah. I also received some information from a gentleman in Canada who built a 7PRC. Did you supply or install the muzzle device or did you get one from Preferred Barrels? They should also understand their own limitations. As an Amazon Associate I earn from qualifying purchases. The numbers arent much better and the only pro I see is getting decent numbers with a shorter barrel. Eh, someday. As we examine the drop and deflection of a bullet it becomes apparent that BC and velocity are very important parameters for shooting at long range. But wait, theres more. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Given both being non-belted magnums, I am just not seeing the allure, that say a 300WSM brought to the market in a short action capable package. Based on the 7mm PRC data you shared, would you use the 7mm PRC for elk and large North American game? If it performs like my 6.5 PRC and 300 PRC, Im guessing it will be a winner too. It has more case capacity than the short, and is very similar to thr max. Trying to decide between the new hot rod 7prc and the old standby (perfect) .280Ackley. The second is errors in ranging and wind doping. There are quite a few variables that all work to decrease the true potential of a rifle. Final load 61.6 grains 1/4moa. Look up bergerbullets.com. Thank you. Most simple ballistic calculators take air density into account, and change the manufacturer's standard sea level Ballistic Coefficient to match the environmental conditions. What are the speeds youre getting with your 20 barrel? Commissions are earned for links to Brownell's, Amazon, MidwayUSA, GoHunt, OpticsPlanet, Sportsman's Warehouse, and other retailers. Great stuff. How do you think it will shoot the Barnes 168 gn LRX in case this new lead ammo ban goes through? Required fields are marked *. As you can see from the above table, the 7mm PRC is most similar to the Gunwerks 7 LRM. Due to the extremely tight tolerances of these cartridges, Ive seen MANY manufacturers struggle with delivering barrels that spike pressures or have brass that doesnt fit right.
