The following are the findings from shooting up to 100 shot groups, as per the following Hornady YouTube videos:
Taking these learnings here is a suggested approach for working up a load for ELR (Extreme Long Range):
Explain this crazy talk!
How variable is my dispersion for different samples sizes smarty pants?
As you increase sample size you funnel your dispersion values into a tighter and tighter band. At some point you will reach a tight enough band to satisfy your expectations.
For example in this rifle system, 5 shot groups vary in size from 0.20 to 1.40 inches, all factors remaining the same. Every gun will pull off a 5 shot quarter minute group if you shoot enough groups, but if you want to know what your system can consistently do, you need to shoot larger groups.
How far off is my rifle’s zero?
If you zero with a 3 shot group, it can be a couple of clicks off in any direction. At extreme long range, this zero error will lead to target misses. A 10 shot group will get you closer, a 20 shot group closer still.
Those busterds just want me to buy more Hornady bullets!
Of course they do.
No one wants to shoot 30 shot groups for every change in a variable. It’s not viable for many reasons including affordability, burning barrels etc.
However hopefully what they have learned, and shared, by burning up tens of thousands of rounds is give you the data you need to come up with a strategy for working up a good handload for your own ELR rifle system, with a good zero angle, to avoid making costly assumptions and adjustments with 3 and 5 shot groups.
The following information is for those engaging targets and/or animals at ranges far beyond what until relatively recently was considered consistently achievable.
As you stretch out to engage targets at 1000, 1500, 2000, 2500, 3000 yards it becomes critical to have precise inputs for your ballistic solver, and set a highly precise zero angle (not zero distance) for your rifle.
You are also stepping beyond the capabilities of traditional Ballistic Coefficient based ballistic solvers which take a limited number of inputs and base their calculations on a standard bullet profile which doesn’t sufficiently match the projectile you are using.
For a ballistic solver to return the correct dial up at long ranges it requires more input parameters than a BC based calculator, in conjunction with high resolution in-flight data for the actual projectile you are using. An example of such a solver is Hornady’s 4DOF, which utilises doppler radar acquired data for several bullet manufacturer’s projectiles including its own.
What are the issues with setting a zero distance and using BC based solvers at very long ranges?
How do we address the above issues?
In conjunction with environmental inputs, an accurate muzzle velocity, and several other inputs your solver will now give you a precise scope dial up.
Can you say “First round hits on target”?
Several aspects of reloading are influenced by statistical considerations, particularly in terms of achieving consistency and predicting performance. Here are some aspects of reloading that involve statistical considerations:
1. Velocity and Standard Deviation:
Velocity, or the speed at which a bullet travels down the barrel, is a crucial factor in ammunition performance. Reloading manuals often provide average velocities for specific loads, and reloaders use statistical measures, such as standard deviation, to assess the consistency of velocity across a batch of reloaded cartridges. A lower standard deviation indicates more consistent velocities, contributing to improved accuracy.
2. Group Dispersion and Accuracy:
When assessing the accuracy of reloaded ammunition, reloaders often measure the group dispersion, which refers to the spread of bullet impacts on a target. Statistical analysis of group sizes helps reloaders understand the consistency and precision of their loads. Smaller group sizes indicate greater accuracy and consistency.
3. Powder Charge Weight and Consistency:
The weight of the powder charge in a cartridge significantly affects ballistic performance. Reloaders aim for a consistent powder charge to ensure uniform pressure and velocity. Statistical analysis, such as measuring the standard deviation of powder charges, helps reloaders gauge the degree of consistency in their reloading process.
4. Bullet Weight and Uniformity:
Bullet weight consistency is critical for achieving predictable and reliable performance. Statistical analysis is applied to assess the uniformity of bullet weights within a batch. Deviations from the average weight can be measured to ensure a consistent ballistic performance.
5. Primer Performance and Ignition Consistency:
Primers play a crucial role in igniting the powder charge. Statistical analysis may be used to assess the consistency of primer ignition across a batch of reloaded ammunition. This includes measuring factors such as the velocity spread caused by variations in primer performance.
6. Case Dimensions and Case Neck Tension:
The dimensions of cartridge cases, especially the case neck, impact bullet seating and overall cartridge consistency. Statistical analysis is employed to measure case neck tension, ensuring that it remains consistent across a batch of reloaded ammunition.
7. Extreme Spread and Standard Deviation in Ballistic Measurements:
Extreme spread and standard deviation are statistical measures used to assess the variability in ballistic performance, including velocity and point of impact. Reloaders often use these metrics to evaluate the consistency of their loads and make adjustments to enhance performance.
8. Pressure Signs and Safety:
While not strictly statistical, the observation of pressure signs (e.g., flattened primers, ejector marks) involves assessing consistent patterns associated with pressure. Reloading manuals often provide guidelines on recognizing these signs, helping reloaders avoid over-pressure situations.
In summary, statistical considerations play a vital role in reloading, helping reloaders assess and improve the consistency and performance of their reloaded ammunition. By applying statistical analysis to various aspects of the reloading process, reloaders can make informed decisions to achieve optimal results in terms of accuracy, velocity, and overall reliability.

There are many fine options for reloading manuals, most from bullet manufacturers who want to provide you with a safe minimum* and maximum** powder charge range for each powder/projectile combination:
* It doesn’t seem intuitive but not enough gun powder is also unsafe. Enough pressure needs to build to expand the cartridge case to form a gas seal in the chamber to stop rapidly expanding gases blowing back in the shooters face.
** Stick within the minimum and maximum charge weights in the reloading manual, they aren’t some bullshit lawyer mandated range, they are a range that will produce safe reloads, confirmed using precise chamber pressure measuring equipment not available to the typical hand loader. The absence of flattened primers, ejector marks, or bulged cases does not guarantee that the load is within safe pressure limits.
Reloading ammunition, or handloading, has been a practice embraced by shooting enthusiasts for decades. While some may view it as a meticulous and time-consuming task, there are several compelling reasons why individuals choose to reload their own ammunition.
