Not all bullets are Max-Range bullets. Lol. But, everything has to be perfect for it to work. This means that velocity is the big player effecting how much a bullet will drop. A faster twist in the rifling of a barrel allows the bullet to spin more quickly to stabilize longer (and consequently heavier) bullets. This difference in bullet shape can be quantified, and the comparison simplified to one numberthe Ballistic Coefficient, or BC. Using dies from Whidden, I got to work. Most simple ballistic calculators take air density into account, and change the manufacturer's standard sea level Ballistic Coefficient to match the environmental conditions. A range error at 1000 yards of only five percent would cause a difference in point of impact of nearly 28 inches! This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. John B. 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. He is a well-known entrepreneur, having started many successful online brands, and lives in St George, Utah.

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. This free bore acts as a gas expansion chamber, maximizing velocity due to a longer pressure curve. There are no bullets below the 0.284 caliber with a ballistic coefficient higher than the 7mm. All the scopes I like seam to be out of my price affordability. Mainly, because of our inability to directly quantify wind speed and direction as we can with distance when using a rangefinder.

Should be the next level do it all cartridge. Shoot! Use a small level, and look closely at new rangefinders that incorporate incline shooting compensation. Decreasing wind deflection is a very important part of precise long range shooting. 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. 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.

It was an exciting huntwe would spot goats from the valley floor, and climb 3000-4000 feet every day to hunt them. 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. 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. In addition to expanding reliably, a bullet must carry sufficient energy to take down the animal. RCC brass is the only place that has it, but the prices are wild at $6 per piece. 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. That adds up to a difference of point of impact between shooting east and west of nearly seven inches.

Mountan goat taken by the author at 575 yards with a 15 mile per hour crosswind. So, the crosswind velocity and the bullet's time of flight will determine how much it is deflected in the wind. The time of flight is dependent on shape (BC) and initial muzzle velocity. Your email address will not be published. However, its pointless to attempt such shots if you dont optimize 7mm Rem Mags point blank range during sighting-in. They use Berger 168 gr VLD (Very Low Drag) bullets. Hey Jim, thanks for all the great content. I converted a Weatherby 6.5 PRC Meateater to the 7 PRC. The ballistic data below was calculated with a Hornady 180gr ELD-Match 7mm bullet fired at . Ive done a significant amount of handloading and reloading for the 7 PRC over the last few months. Love the Channel!!! Thanks. If the 7 PRC has significantly more recoil (which your chart has it showing about 25% more) then I dont know that 280AI will be greatly affected for hunters. I will likely switch to that bullet once it becomes available. In fact, it may be about the best choice on the market for my personal preference. 5/8 to 1 groups at 500 yards. As an Amazon Associate I earn from qualifying purchases. 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 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.
