The reason that the bullet deflects, is because its initial flight path or direction is different from the wind vector and resulting bullet attitude. If I add to that a gusty 25 mph wind, Im not shooting past 200 yards. 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. on steroids. Decreasing wind deflection is a very important part of precise long range shooting. It has more case capacity than the short, and is very similar to thr max. I ABSOLUTELY would use 7mm PRC on elk. This spring I built a 7mm REM Mag with a long throat in a 28 inch barrel 1:8 twist from McGowen Barrels. Thankyou for report off the 7mm PRC as I have been searching for since I saw the SAAMI specification. It is intended for long-range shooting due to its ability to utilize high BC bullets, and is also uniquely suited for hunting large animals such as elk. I mentioned that a bullet may not perform well under 2,000 fps. I have one on order with Preferred Barrels. I guess I can hang the gun on the wall and admire its looks until ammunition is available. I was pleasantly surprised to see that the cartridge is quite mild. Loaded with IMR 4830 @ 70 gr. These guys have 7mm rem mags taking elk at 900+ yards. H1000 ran out of space for powder before I reached max velocity. it works. @Jim Harmer I know this is a very hard list to compile, I do appreciate your attempts to educate in a common sense way. I was looking at having Preferred Barrels make me a 7mm PRC similar to what you have shown. .460 Steyr .416 Barrett .408 Cheytac .375 Chetac etc. While the 7mm 168 grain VLD would only need 3100 fps at the muzzle to match that 2000 fps velocity at 1000 yards. All the scopes I like seam to be out of my price affordability. Please keep the good stuff coming. What is the mounting method, QD or threaded? However, its pointless to attempt such shots if you dont optimize 7mm Rem Mags point blank range during sighting-in. 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. Re#26 69 grs pushes a 162 gr A- max 3225 fps. Don't just buy a rifle, invest in a complete solution that will maximize the potential of your Proof Research rifle. burning 61 grains Reloder 22 Recoil: 26.5 ft-lbs at 14.6 fps velocity Muzzle Energy: 3,269 ft-lbs Maximum Pressure: 61,000 psi MPBR: 365 yards (Zero at 307 yards, 3.9" high at 100 yards) These are some impressive numbers. The amount of wind deflection is basically determined by how large the drag forces are and how long those forces act on the bullet. Interestingly, I loaded 61.2 grains of H4831SC in a 7mm Remington Magnum, and a 7mm PRC. To optimize performance of the 7mm RUM, Remington engineers produced a chamber design utilizing .400" (10mm) free bore. I chose to put a Proof barrel on and had an M16 extractor installed and am very happy with the results. In fact, Id guess that 60% of the new hunting rifles in most gun stores today are chambered in a cartridge designed by Hornady. Does anyone know how hot you can load a 162 gr. The benefit was a hot shower and soft bed every night! Your results may vary. i have a 6.5 prc after reading this page on 7mm prc theres not enough extra hump in this new prc to justify buying one, I have three 7mags but I also have a 300wsm that lays down the gauntlett and beats this prc at everything. Love the Channel!!! That is more recoil than a .30-06 but less than a .300 Win Mag. Thank you for your efforts and info on this. Thats a dead whitetail deer out to 1200 yards lol. It resists wind drift well. While I like and support new cartridges, does the PRC provide anything new? 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. 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. The list goes on. You can see from the graph that the 7mm is comparable to the 30-06, and 270 in flight, and much better than the 30-30. Your email address will not be published. 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. Heres that data using his 24.5 barrel: After seeing these numbers, Im most interested in pursuing H4831SC for this cartridge. Mag. Not all bullets are Max-Range bullets. https://bobp.cip-bobp.org/uploads/tdcc/tab-i/tabical-en-page36.pdf. Youre right. I thought for certain it would have more powder capacity than a 7 Mag so Hornady could advertise the new cartridge beating the old standard. By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. With the high BC of some of the 7mm bullets, ballistically this 7mm PRC will outshine most 6.5mm and 30cal cartridges. Im sure people will certainly use the cartridge for many things. there are plenty of rifles capable of 1000 yards but if your looking for something that wont drop 10 ft there are better choices. Worked up load with 195 bergers. Here is the above load showing the trajectory out to 500 yards based on those optimum sight settings: At 500 yards this bullet is only 29.14 inches low! For this ballistics demonstration we are using Norma 150gr Scirocco with a muzzle velocity of 3117fps and a ballistic coefficient of 0.536. In the 1960's Remington created the 7mm Remington Magnum based of the 375 H&H cartridge design. RCC brass is the only place that has it, but the prices are wild at $6 per piece. That adds up to a difference of point of impact between shooting east and west of nearly seven inches. I just finished my 7saummight need to do an identical build but in 7prc and compare. 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 have a complete article on the best rifles available now in 7mm PRC. Thank you very much in advance, Did you supply or install the muzzle device or did you get one from Preferred Barrels? I really want to compare recoils of suppressed rifles. Very impressive ballistics. If you own a 7mm Rem Mag, its easy to produce 7mm Rem Mag Ballistics reports using Shoot! Simple as that. Great video and Ive been following and hoping that a 7 PRC would come for years now. 7mm Remington: SP: 203: 2447: 2330: 7mm Remington Youtube is full of those videos. I had them make me a short 20 carbon fiber-wrapped barrel chambered in 7 PRC. same principal applies to bullets. I will likely switch to that bullet once it becomes available. Ive left comments but could use some advice. Magpro had a lot of case capacity left, but wasnt getting the velocity Id hope to see without just burning a ton of powder. Backfire was the first publication to put together a 7 PRC as soon as the SAAMI specs for the cartridge were released. You have stated several times you would not use 6.5 Creedmoor or 6.5 PRC for large game like elk. The specified twist rate for each cartridge dramatically impacts the ability for a firearm to spin a bullet fast enough to stabilize a long bullet in flight. Hi Jim, Im a follower on YouTube, I really enjoy all of them. Maybe yall will find some magic power that will do likewise for the 7mm prc. Did you perhaps mean 50 cm? Personally, I have said for a long time on the Youtube channel that my ideal hunting cartridge would be a 7mm shooting 180 grains at 3,000 fps. Freedom is not free. Flat nosed pistol bullet on the left, .308 Cal 168 grain Barnes TSX center, VLD shaped 7mm 168 grain far right.But it doesn't take a huge difference in bullet shape to have a big effect when we are comparing velocities over 1000 yards. Jim, Im wondering why you did not include the Winchester 284, in your comparative with the lineup. Personally my mind goes towards hot rodding medium-to-heavy-for-caliber monos in the 150-175 grain range at 3200 -> 3000+ for long range expansion on game. Next, I loaded H1000. You did not compare this cartridge to the 7mm RUM? The two most important variables are the Initial Velocity and the Ballistic Coefficient. Most people will like 22, but I like em short! 7mm Rem. Ciao Jim caccio in zona Alpi in Italia cammino molto e vorrei un arma leggera . Thanks for all the helpful info on the 7PRC. Also, remember that the data in the table above is using averages of multiple loads per cartridge. Initially, I expected H1000 or Retumbo to be the best powders for the 7 PRC since they are fan favorites of the 7 Mag. Depending on bullet type and construction, the minimum expansion velocity for rifles falls between about 1300 and 2000 fps. What are the speeds youre getting with your 20 barrel? This bullet with a muzzle velocity of 3000 fps in a 10 lb shooting system, with proper stock design is about a maximum level of recoil a long range hunter should deal with. You have to find the right balance of weight and aerodynamics. Being derived from the H&H case, there is plenty of case capacity, and the 7mm Remington Magnum will send the heavy 175-grain bullets at a muzzle velocity of 2800 fps or so, depending on the manufacturer, and the speed only increases as the bullets get lighter. But wait, there's more. tells us to sight-in this load to shoot 2.37 inches high at 100 yards for a 255 yard zero. We know the grain is different but that's as close as we could get with the Winchester Silvertips. I was somewhat surprised by the list of firearms manufacturers who are not yet jumping on board with the 7 PRC. One of those limitations is shooting system portability and that goes hand in hand with recoil and muzzle blast. Policy. Unfortunately, no. This free bore acts as a gas expansion chamber, maximizing velocity due to a longer pressure curve. Humidity plays an almost negligible role. Graph below shows the energy remaining at 500 yards for the same load: At 500 yards the remaining energy is 1710 Ft-Lbs. If you own one of these items you are free to ship them to us for programing. If it performs like my 6.5 PRC and 300 PRC, Im guessing it will be a winner too. Jim Harmer is a host of the Backfire Youtube channel. I watch all your videos. I also have a 264 mag but the 6.5prc will do anything it will do but with a lot less powder. I really enjoy every bit from Income School! It is on the upper end of what most large adult shooters can comfortably tolerate. Heres a link to it. The heavy weight 7mm projectiles can be used on the lightest of game through to animals weighing up to 320kg, producing fast clean killing out to 1000 yards. The 7mm Precision Rifle Cartridge is a long-action centerfire rifle cartridge designed to shoot 180 grain bullets at 2,950 fps. 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. In general, a bullets maximum effective range is the distance at which it no longer travels fast enough to reliably expand when it hits a target. 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? The challenge of loading for any of the PRC cartridges is the extremely tight tolerances. A 20 degree incline at 1000 yards is worth 15 inches and is a realistic shooting situation. The 7mm PRC will beat the following cartridges in sales over the next 20 years: 280AI, Gunwerks LRM, and the 7mm Rem Mag. Required fields are marked *. The 7mm Rem Mag is available from 139-175 grains, while the .300 Win Mag is available anywhere from 15-230 grains. 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. Power Rank: 3.9 of 20. Testing 160-168 Gr bullets. Input your hunting conditions to see the drop, drift, bullet trajectory, velocity, and energy in easy-to-read ballistics charts and graphs. Nice informative article. Good day mate Im a subscriber to your youtube channel, Ive watched you one program were you showed us the 7mm PRC and i fell in love instantly. This setup is for long range target shooting. Whidden Gunworks doesnt show 7mm PRC offering on their website. ( I know you prefer shorter barrels especially for hunting). Seldom is the practical max the same as the true max distance. con canna da 50 inch. This is again shooting the 175gr ELD-X bullet out of 24 test barrel with a large magnum CCI primer. Last, I shot Accurate Magpro powder with the same 175gr ELD-X and CCI large magnum primer out of a 24 test barrel. This is averaging several different loads to get these numbers for each cartridge, so we can compare apples-to-apples, but youre right that with ALL cartridges you could go up or down slightly depending on the load selection. Mainly, because of our inability to directly quantify wind speed and direction as we can with distance when using a rangefinder. Awesome article and information. Commissions are earned for links to Brownell's, Amazon, MidwayUSA, GoHunt, OpticsPlanet, Sportsman's Warehouse, and other retailers. 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. We develop the ideal load for your rifle that is tailored specific to your requirements, hunting or target. The best of us always leave too soon. Thats when little things cause failures. Im hunting with this cartridge with 145 gr TTSX on red stags till 250 kg untill 300 m: I quickly saw that the 4 fewer grains of case capacity in the 7 PRC made these powders not ideal. Itll get tons of penetration and you could shoot that light of a bullet VERY fast. Or, you can of course use a custom action like a Terminus, Defiance, etc. Well, that would limit most hunting rifles to between 150 and 400-yards. Mag. My scope has seen better days but my Weatherby Accumark is like new and I really like it. Wind deflection, or drift as we usually refer to it, does not occur from wind blowing on the side of the bullet. They gave me a 22 inch 7MM barrel blank so thats what I used for my 7 PRC build. .308 Winchester 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? Custom Ammo:Upon request we can provide you with custom loaded ammunition. Do you have any MV numbers from your 20. This bullet has massive power, and a really flat trajectory allowing this bullet to hit targets much further away and with more power. Surprisingly, the factory ammunition for the 160gr CX bullet offers the same 3,000fps muzzle velocity as the 175gr ELD-X bullet. Ok ya that makes sense. I guess the 7mm WSM is dead. A bullet with a BC of 0.400 will drift over 40 inches at 700 yards in a 10 mile per hour crosswind. 1400 W Henry St 375" drop w/ 100 yard zero. Why is it a foregone conclusion that Shooters will gravitate toward heavy-for-caliber high-BC bullets in the 7mm PRC? Eh, someday. If you throw a big rock, it puts a big hole in the ground, but doesn't go so far. If you throw a big rock, it puts a big hole in the ground, but doesn't go so far.
