Quanto pesa il sistema che hai realizzato? Looking forward to seeing what the 7mm PRC can do by comparison. The benefit was a hot shower and soft bed every night! 7mm Remington Magnum Despite its age, the 7mm Rem Mag's ballistics perform well even by today's standards. rating at 4,200 fps, it would miss. Is that right? After that velocity diminishes very quickly. Question, should I consider a 22 for the added benefit of when non suppressed or will the 20 (non suppressed) handle my needs just fine. The Precision Rifle Cartridge line is now broad enough that for many hunting uses, shooters will have a tough time deciding between the 6.5 PRC, 7 PRC, and 300 PRC. I hope brass makers continue to make 7mm STW brass. They sent me their full-length bushing resizing die and micrometer seating die and Ive been amazed with the quality. (About 19.5 inches). Input your hunting conditions to see the drop, drift, bullet trajectory, velocity, and energy in easy-to-read ballistics charts and graphs. Lol. To make it as accurate as possible, it is important that you input the most accurate information that represents shooting conditions, your firearm, and cartridge. 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. I reload and would be VERY interested in learning more about being able to use less powder to achieve higher velocities with the the same bullet in 7 PRC vs 7 rem mag. I used CCI large magnum rifle primers, and lovingly caressed each bullet before sending it on the ride of its life. The 7mm Precision Rifle Cartridge is a long-action centerfire rifle cartridge designed to shoot 180 grain bullets at 2,950 fps. Figure 2. Download Shoot! 61.6 grains H4831sc. 66 grs of H1000 behind a Berger 184 Hybrid produces 3,000 fps. for a 6 inch vital zone (typical of a whitetail deer). Please use a 300 yard zero and give me 100 yard clicks out to 1000 yards. There is still quite a bit more case capacity left with Magpro (my guess would be you could go to 77 grains before it compresses), so that could be an option for max velocity, but youd be going through quite a bit more powder to get there. I would like to know if you have any info on the 7.7 jap. They use Berger 168 gr VLD (Very Low Drag) bullets. Using this as a reference, let's examine several other factors that can effect our shot placement. Shots near the max effective range can totally miss the animal if you misjudge the distance by 50-yards. On that same goat hunt, I missed a longer shot because I didn't read my terrain perfectly, and an updraft caused me to shoot right over his back. While the 7mm 168 grain VLD would only need 3100 fps at the muzzle to match that 2000 fps velocity at 1000 yards. The same goes for doping wind for direction and speed. I am alarmed at the number of proponents of long range shooting technology that simply ignore the effect of wind, and have no provision to compensate in their equipment. Seriously, its by far the nicest die set Ive ever ownedand Ive tried just about every brand out there. Even fairly experienced reloaders sometimes struggle to get reloaded brass to fit properly into the rifle. Jim Harmer is a host of the Backfire Youtube channel. But wait, there's more. lb Muzzle Velocity ft/sec. Love your channel and style. But this is where atmospheric affects come into play. Just imagine a long slender VLD bullet compared to a flat nosed semi wad cutter. Sorry man, wasn't going after anyone, it's a hotly contested issue around the guys I run with, guess i just assumed it would be here too. 5/8 to 1 groups at 500 yards. Magpro had a lot of case capacity left, but wasnt getting the velocity Id hope to see without just burning a ton of powder. I apologize for the misunderstanding. The Bigger Question is, whats YOUR maximum? Do not rely on my anecdotal testing for your rifle. Seems like the 7 PRC is 90% of the 28 Nosler without the extremely short barrel life and 20% less recoil. The numbers for hunting bullet's usually range from 0.200 to 0.800 with most falling in the 0.400 range. We carefully monitor the velocity until we see a significant increase (30-60 fps) which usually takes around 40 to 60 rounds. If your max is 400-yards and the deer is moving, perhaps stick to 200-yards. Suggested 7mm Rem. while they work great at closer ranges, they will fail miserably if you want to push your shots out there. I have an m70 classic with a 26 Brux barrel. No obvious pressure signs, but I didnt feel I should compress further. Use a small level, and look closely at new rangefinders that incorporate incline shooting compensation. The list goes on. .270 Winchester Short Magnum, .30 M1 Carbine, .300 H&H Magnum, .25-06 Remington, .284 Winchester, .224 Weatherby Magnum, 7x57mm Mauser, .250 Savage, .405 Winchester, .45 Colt (often called .45 Long Colt), .375 Dakota, .375 Remington Ultra Magnum, 6.5mm Remington Magnum, .500 Smith & Wesson Special, .375 Holland & Holland Magnum. Ballistic Programing/Custom Turrets:If you are buying a ballistic range finder or kestrel we will program the ballistic computer for you so everything is ready upon arrival. She looks like a real keeper to me. What is the mounting method, QD or threaded? I think Hornady just hit another home run with this one. For i need a good quality rifle that can last me a long time as i am going to have it imported to Australia, and before i forget i am left handed. But wait, theres more. If its foggy or rainy out, the clarity of your sight picture will limit how well you can shoot. Would like to see this compared with the .30-06 and .308. Again, weight of the bullet plays a large role in bucking wind. 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. Please keep the good stuff coming. 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. Snow. Just wondering. It would have been nice had you included the bullet used, bullet weight and muzzle velocites, because as we both know these vary a great deal. The illustration in Figure 3 was reproduced from Harold Vaughn's excellent book Rifle Accuracy Facts, and shows how a bullet reacts, and the drag forces that cause wind deflection. This is usually about 1,900fps with most bullet designs. Thank you very much in advance, To do load development before this speed up happens will render the load development useless. V-MAX . Why is it a foregone conclusion that Shooters will gravitate toward heavy-for-caliber high-BC bullets in the 7mm PRC? 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. Windage differences are still within 2 inches. Unfortunately I wasnt able to find any standard case diagrams for the Sherman cartridges so thats really all I can say. Whidden Gunworks doesnt show 7mm PRC offering on their website. I have a winchester model 70 in a 7mm mag if im shooting 100 grain bullets what kind pf drop would i expect at 1000 yards. 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? Heres what he reported using a 175gr ELDX, Federal 215M primers, and Reloder26 powder. Thats one flat shooting load considering we sighted-in the bullet to impact only 2.37 inches high at 100 yards. Would also mention- at THAT range, your ability to "read the wind" becomes critical. The other major factor is bullet availability. Thankyou for report off the 7mm PRC as I have been searching for since I saw the SAAMI specification. A good laser rangefinder is a tool, and if it isn't used properly it won't yield good results. 7mms in general produce such good ballistics like higher retained velocity, energy, etc because of the bullets made for this caliber. Ive been working with some pre-production brass that isnt very good. A bullet with a BC of 0.400 will drift over 40 inches at 700 yards in a 10 mile per hour crosswind. I have a complete article on the best rifles available now in 7mm PRC. Thank you. 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 . Thanks, Jake. The 7 RM is too established to go away similar to how the 300 PRC didnt completely eliminate 300 WM sales nor did they likely affect 30-06 sales. You should try Vihtavouri N560 powder in your 7 PRC. Did you perhaps mean 50 cm? I appreciate this information. For example, having 1,500 ft-lbs of energy to kill a bull elk is a decent barometer, but elk have also been killed with far less energy when excellent shot placement and good bullet construction are in play. Eliminating the effect of wind by using high BC's and proper compensation techniques is the only solution. 7 PRC looks like the best large deer caliber. Thanks for your help!!! Id love to see what data you get so I can include more data in this post. Just like shooting near dawn or dusk, or shooting into a glare. Oh, it would be close, but it would still fall under the precise point of aim by about an inch. How does the 7mm Rem Mag achieve such ballistics? My $0.02, 6.5 creedmore, 7.82 warbird, 338 luapa, 7mm ultra mag comes to mind. Cartridge Type: RifleHeight: 2.5"Width: 0.532"Average FPS: 3024Average Energy: 3106Average Gr: 153Recoil: 2.06Power Rank: 4.63 of 20. A rule of thumb I use is if an animal is walking, shots need to be twice as close. Remember, they dont show you the times it didnt work. Graph below shows the energy remaining at 500 yards for the same load: At 500 yards the remaining energy is 1710 Ft-Lbs. 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. Exact same setup. If for a brief fraction of a second everything is lined up and you in that instant know you got it, take the shot. If you want to max things out, you need a bullet that will expand at lower velocities. Mainly, because of our inability to directly quantify wind speed and direction as we can with distance when using a rangefinder. It is on the upper end of what most large adult shooters can comfortably tolerate. Should be the next level do it all cartridge. I just hope I gave you a little something to consider. (They are the only company that has any 7PRC brass that I know of. I just completed my 7PRC build, and have started testing. However, hunters who choose to use gear that does not meet this standard are often forced to either make an unethical shot or to pass up shot opportunities when the elk isnt turned the right way. As a competition gun and a capable do all cartridge the 7 PRC absolutely checks just about every box there is I look forward to adding it to my 7mm-08 (for 120-150gr bullets) and 280AI (for 140-175gr bullets) as a capable 7mm magnum that isnt tremendously overbore and specialized for heavier (160gr+ bullets). Look up bergerbullets.com. Heres that data using his 24.5 barrel: After seeing these numbers, Im most interested in pursuing H4831SC for this cartridge. For example, most of the all-copper expanding bullets need something like 1,900 0r 2,000 fps to expand even a little. The ballistic data below was calculated with a Hornady 180gr ELD-Match 7mm bullet fired at . However, why was the 8mm Mauser left out of this comparison? Using a 30 Bartlein barrel, Manson reamer, RCC brass, and wanted to do some comparisons to your results. This free bore acts as a gas expansion chamber, maximizing velocity due to a longer pressure curve. Further comparison shows that is flies faster than either of the 3 other rounds, and only the 270 Win beats it in terms of average power, but the 7mm is the victor in the average energy as well having 3106 lbs of force from muzzle. Was pleasantly surprised by your reference to preferred barrels and to find out that you are also a local Utah sportsman as I grew up only 70 miles away from St. George and still live and hunt this area with my family. My 7 PRC will be in my hands Thursday so I will let you know how N560 and a 175 Hornady ELD-X does. 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? personally I like the 338 luapa and the 6.5 creed, reasonable to shoot compared to a 50 bmg and they will get you out there where you want to be and dont skip on the glass , high quality glass and big power isnt cheap either. Will be suppressed at times, but in a effort to save weight on certain hunts will ditch the can(7 TBAC Ultra). I see yours has a suppressor. Ciao Jim caccio in zona Alpi in Italia cammino molto e vorrei un arma leggera . Now, if we could just shoot a bullet with a BC of 0.800 at a muzzle velocity of 4000 fps, we would have an awesome long range hunting round! The 30 caliber 165 grain Barnes TSX would have to be fired at 4100 fps muzzle velocity to maintain 2000 fps velocity at 1000 yards. Shot placement, bullet construction, and animal individuality will all dramatically impact the effectiveness of the bullet. You mentioned that length. Hornady has an incredible track record with cartridges over the last 20 years: 6.5 Creedmoor, 6.5 PRC, 300 PRC, 17HMR. All the scopes I like seam to be out of my price affordability. Red Oak, White, or Chestnut for Deer Herd? 7mm Remington Magnum ~ 150 Grain ~ Trajectory Chart Trajectory for Custom .284 7mm Mag Ammo #4550 at 3000 Feet per Second At an Elevation Angle of: 0 degrees Ballistic Coefficients of: 0.545 0.515 0.515 0.515 0.515 Velocity Boundaries (Feet per Second) of: 2200 2200 2200 2200 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 always run a suppressor would like to see 20 with suppressor vs 24 with break. In a trophy hunting situation, it's important to have the equipment and preparation to ensure that you can make the shot at that once-in-a-lifetime trophy, even at 800 yards! I did chamber a 7mm Blaser some years back, the 7mm PRC seems to me a very much balanced cartridge coming from the 78gn capacity and based on the Ruger cartridge, look to be efficient for loading 160gn bullets to 2900-3000ft/s. same principal applies to bullets. It has more case capacity than the short, and is very similar to thr max. Newlon blanks. Up and down winds can be tough to deal with because of difficulty in reading mirage, or the terrain can be hidden. .460 Steyr .416 Barrett .408 Cheytac .375 Chetac etc. 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? what speed can you get? With quality hunting ammo, this cartridge maintains 2000 fps velocity to around 600 yards. Basically, like a wind vane on a roof or windmill, the bullet will align itself with the prevalent wind. I really do like what you and your contributing crew are doing. They use Berger 168 gr VLD (Very Low Drag) bullets. I do have a gain lands so its not a 100% apples to apples comparison. @Jim Harmer I know this is a very hard list to compile, I do appreciate your attempts to educate in a common sense way. So youre telling me Springfield Armory is planning on making a 7 PRC Waypoint 2020 in 2023 ?!?!?! It's like these other guys said, if you throw a small rock it goes really fast, but not very far. I find your data a bit too limited, which can vary greatly depending on multiple other factors. Hopefully more options than what the 6.8 Western. L. B. 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. I quickly saw that the 4 fewer grains of case capacity in the 7 PRC made these powders not ideal. Apr 17, 2011. load. But, everything has to be perfect for it to work. do you know the 7mm Blaser Magnum? Still havent been able to find brass. Before SAAMI drawings of the 7 PRC were released, I fully expected the 7 PRC to follow the industry-wide trend of overbore hot-rod cartridges. Great cartridge. 7 PRC is designed for shorter barrels. These are Altitude (basically, Pressure), and Air Temperature. The Extreme Spread (ES) of our velocity is usually under 10 fps and Standard Deviations (SD) is usually around 3-5 fps.
