A hunting firearm can only be so heavy, and a smart shooter will only subject himself to a limited amount of recoil. The bullet does not drop below the speed within the max range specified. 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.

That is more recoil than a .30-06 but less than a .300 Win Mag. 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. A good marksman will not squeeze the trigger unless he believes it will work. 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. You can find an email form and contact information here. Now im gonna say this , without reloader 26 powder I would have no need to own this 6.5prc, this powder is like magic. Select Your Gun Type.

To optimize performance of the 7mm RUM, Remington engineers produced a chamber design utilizing .400" (10mm) free bore. However, its pointless to attempt such shots if you dont optimize 7mm Rem Mags point blank range during sighting-in. Max range 600yard, would like to shoot the 180s.

Backfire LLC owns and operates this website. I also have a 264 mag but the 6.5prc will do anything it will do but with a lot less powder. I feel it will offer the best velocity in a shorter barrel. They use Berger 168 gr VLD (Very Low Drag) bullets.

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. Why is it a foregone conclusion that Shooters will gravitate toward heavy-for-caliber high-BC bullets in the 7mm PRC? 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. 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. He has managed multiple gun ranges, and has hunted around the world. If you want to max things out, you need a bullet that will expand at lower velocities. 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. 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.

Hey C3, Aren't Bases for long range higher in the rear as to give better muzzle elevation to scope alignment? If you do not have a Shooting Chronograph, I strongly suggest you purchase one. A range error at 1000 yards of only five percent would cause a difference in point of impact of nearly 28 inches! The time of flight is dependent on shape (BC) and initial muzzle velocity. The 7mm, however, seamlessly made the transition to . 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 watch all your videos. The best of us always leave too soon. 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.

They should also understand their own limitations. Cartridge Type: RifleHeight: 2.5"Width: 0.532"Average FPS: 3024Average Energy: 3106Average Gr: 153Recoil: 2.06Power Rank: 4.63 of 20. Im tired of hunting with my long and heavy 300 win mag so Im re-chambering it. Depending on bullet type and construction, the minimum expansion velocity for rifles falls between about 1300 and 2000 fps. My prediction? Unfortunately, as hunters we have other limitations that force us to settle for equipment with lower BC values and muzzle velocities. You mentioned that length. Important Note: This is anecdotal testing. First know Im a disabled hunter who is in my early 60s, I have a spinal issue from an accident and just had shoulder surgery, I cant walk far anymore. Ive got it sending the 162 grain ELD-X 3200 FPS. Once break in has been achieved we clean the rifle and begin load development. The 7mm Rem.

This difference in bullet shape can be quantified, and the comparison simplified to one numberthe Ballistic Coefficient, or BC. Obviously, there are many technical differences between the two, but they do fill a nearly identical hole in the market. By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. Barrel Break In: All barrels will increase in speed. Larry Whitehouse. Im just looking at the brass for symptoms of being over-pressure, but sometimes those symptoms dont show up until a cartridge is significantly overpressure as could be measured by a computer.
