FEATURES & INTEGRATION - DESKTOP & MOBILE & PHONE
editions are designed as a set of tools, herein called Modules,
in order to conform a specific-purpose software suite, where feature-based
integration is the key design concept.
A comprehensive, accurate and practical software
solution for the reloading and ballistics enthusiast. With just one
focus : to cover in a single package all the necessary tools that a
challenging user is looking for.
Its main purpose is to help the centerfire metallic
cartridge Reloader / Shooter / Hunter with the most common tasks often
involved in shooting which implies to be able to predict accurate
exterior ballistics, developing a load or analyzing and storing field
data, as well as searching for tested loads.
The user’s experience, as a critical factor, is at
the center of the software's architecture.
Easiness, a practical sense of use, and the notion of
sharing a common paradigm of operation, were considered factors of
paramount importance and so incorporated in every feature of this
This is a professional-grade software, for demanding users, who only
want the best and take great efforts to master the Art of Accurate
It was conceived from the ground up as a set of
practical, smart tools for the shooter to make the most out of his
rifle/ammo and to maximize the probability of a first-shot impact on
target at range.
However it's important to consider that there are no
miracles or mathematical models that can deal with inappropriate data
input and lack of effort in collecting the most exact possible values of
both the environmental conditions as well as the gun parameters.
Its scope is broad, as well as its audience, being a
valuable toolbox for competitive shooters, hunters, forensic experts, in
short, anyone interested in this fascinating subject.
Here the user will find a set of functionally-based
modules to assist in almost every conceivable shooting/hunting scenario,
including the special challenges ever present in Long Range Shooting.
All the hard-to-find parameters needed to analyze and
compare different loads are available at the user’s fingertips
complemented with Reports, Graphs and Filtering features, as well as
packed with many other utilities, closing the circle in the development
cycle of reloading, gun testing and field shooting.
Finally, we can attest for sure, that this software
was conceived to serve as a one-stop Ballistics/Reloading solution.
It is made up of 8 (eight) Modules (depending on edition), designed
and programmed to be fully compliant with the guidelines of
a Microsoft® Windows-based application.

a full featured module designed to manage and perform analysis on
all data collected from a shooting session or when testing a new
load. Its electronic format will keep load data, target data and
velocity data, coherently organized into a neat and easy to use
It’s intended to help users to store, search
for and retrieve all data from a reloading and/or shooting
session, without any hassle, in order to keep an "electronic
log", plus a powerful array of options manage the data so
necessary for any reloader.
All data stored in a relational database.
A single, consistent interface, for
storing, updating, searching and sorting records.
Multiple selectors for choosing
Easy and immediate, velocity statistics.
A complete graphical interface to store
target’s data, with 20 grid styles to choose from, plus
the option to store an actual target's image.
In short, a neat way to store information about
your loads, and field or range results. Take into account that
only from past records a handloader can gain insight about his
professional Exterior ballistics module. Its primary purpose is to
compute a bullet's downrange data for up to 6 tracks (concurrently),
and up to 3000 yards/meters.
Data synch with Mobile & Phone device
Specifically designed to perform ballistics
analysis, unleashing the inner aspects of gun/cartridge
performance, and to "play" with multiple parameters in order to
obtain valid conclusions, perform sensitivity analysis by
modifying variables, etc. all of this using an advanced
ballistics engine that is state of the art.
Multiple independent tracks makes easy to ask
"what if" or "what happens" questions, allowing the analysis of
different shooting scenarios.
ColdBore© Desktop edition six independent tracks let you see all
the results at the same time either in tabular format ( as
numerical values ) or as graphical plots.
Of course, all data could be stored and later
recalled, in the program’s database.
You can specify one set of atmospheric
conditions for sight-in, and another set for a different range
or hunting location and then compute how the original trajectory
will change at the new location.
Its comprehensive functionality allows the user
to calculate all the elements of a bullet's trajectory, and for
any set of firing conditions.
These firing conditions include muzzle velocity
of the bullet, elevation ( or depression ) angle of the gun
barrel, altitude of the firing point, wind conditions at that
location, and environmental ( meteorological ) conditions.
Advanced, state of the art ballistics engine,
for up to 6 ( six ) tracks and Multiple Units Systems.
The calculated trajectory parameters
includes downrange velocity, energy, momentum, drop
relative to the extended bore line of the gun, bullet
path height relative to the line of sight of the shooter,
wind deflection of the bullet, and time of flight of the
bullet, lead for a running target, etc.
The program generates a listing of all
these ballistics results and provides graphs, which the
user can select, of velocity, energy, momentum, drop,
bullet path height, crosswind drift plus target lead and
various tabular formats are used to present the results
in very convenient ways.
Also included is the PBR ( Point
Blank Range ), Danger Space and Hit Threshold calculations,
including the information for making "zero" adjustments
in MOA, MRAD and CLICKS, and for ANY SLOPE.
From that data the module will create, at the
same time, a valuable set of seven ready-to-use Field Charts
especially devised to deal with the stringent challenges posed
by shooting at long range.
Create field charts for Slope, Reticle
Holdover (40 different designs), Mil-Dot distance and a Mil-Dot

this module facilitates the user to perform the most common unit
conversions often needed in Shooting/Reloading.
Categories, such as Length, Volume, Area,
Mass and more.
Since it uses significant figures,
conversions are never inaccurate, and they are in full
compliance with U.S. standards.
Unit Conversion can be a complex problem.
Whether you're trying to handle multiple units systems or simply
converting a single value from imperial to metric units (
International System of Units ) this module has the solution.
Measurement conversion affects all areas of our
sport and with this tool the user will handle measurement
conversion in a consistent and flexible manner.
designed as a set of calculators, ranging
from Interior Ballistics calculations to other related phenomena,
like computing a barrel’s optimum twist, a bullet’s stability
factor, BC from two velocities, BC conversions between different
Drag functions and to calculate the Drag Coefficient as it’s
needed by the ballistics engine.
Its value as a module is central to this
program, which is projected to perform side-calculations that
while not routinely done, are of great importance for the
Powley Calculator : an updated
implementation of the method devised by the late Homer
S. Powley to predict load charges and pressure when data
for a particular cartridge is not easy to find. A nice
complement for the extensive loads’ database provided by
ColdBore 1.0© providing to the experienced handloader a
fast, accurate predictor.
Twist & Stability : an enhanced tool to
compute a barrel’s optimum twist and the resultant
stability factor for a given bullet. Two methods are
used at the same time. A modern one, considered a
breakthrough in modern ballistics, based on the work of
Don Miller ( 2005 ) which has been proven very accurate.
This method considers the effects of both velocity and
air density. The second one was derived from the work of
Sir Alfred Greenhill ( 1879 ), however the current
algorithm was enhanced to deal with new bullet styles
and high velocities. It does not use a constant value
across the range of the different variables.
Chronograph Vel Correction : its
purpose is to correct the instrumental velocity (chronographs
figures ) accounting for the BC of the bullet, its
velocity and the distance between the muzzle and the sky-screens.
BC from velocity : The BC gives the
ratio of ballistic efficiency compared to the standard
G1 projectile as used by the bullet’s makers. This
module will accurately compute any bullet’s BC given its
velocity loss measurement as indicated by two
BC Conversions : since there are many
drag functions that were developed to have a better fit
for same bullet styles, this tool will allow the user to
easily convert one function’s value to another very
easily. A must for those interested in pursuing very
accurate trajectory predictions for the modern,
Drag Coefficient : this module was
specifically added to assist the shooter to determine
the correct value of a critical constant used to
calculate the changes to the drag function over the
supersonic velocity range. In other words, this
program ballistics' engine uses a drag coefficient (DC)
that affects the calculated rate of bullet deceleration.
Applying this DC, the resultant trajectory calculations
are very accurate for that particular bullet because the
drag function has effectively been tailored for that
Recoil Calc : here the user will access
a recoil calculator for up to two firearms, projected to
perform accurate and meaningful comparisons, in both
tabular and graphical layout, featuring an
straightforward interpretation of this central effect.
|| Error Budget
|this module is a tool designed to evaluate the performance of small arms under the light of several analytical tests, like:
The key concept here is to rely on model-based predictions in lieu of physical experiments.
The proper use of this tool will assist in identifying the primary sources of delivery error for direct-fire ballistic projectiles. The term “delivery error,” also referred to as “shooter error”, is a general term referring to the error in delivering a projectile upon a target.
The underlying core provides two distinct methods to carry out the simulation, which are based on sound statistical principles specifically applied to this kind of computer-simulation. The central goal is to mathematically quantify the different metrics, in order to represent the sensitivity of probabilistic statements on data.
To assess a weapon system's accuracy, building an Error Budget is the most technical approach.
An Error Budget can be defined as a systematic description of the sources of error in a system. For this analysis, the system is comprised of the rifle, load, sight and environment, as characterized by its ballistics and performance parameters, while the error is accounted by the bullets dispersion at the target.
An Error Budget is then used to simulate the accuracy of a system, and most significantly to identify the most critical error sources that contribute to the overall dispersion. Three steps are required to design an Error Budget:
* Estimate the magnitude and statistical distribution of the error sources
* Model the mechanism that converts the error source into system error
* Merge errors from a range of error sources.
In simple terms, the Hit Probability P (h) is a statistical value indicating the number of hits being made on a target out of a given number of projectiles directed at the target of a specific size at a determined range. It’s expressed as a percentage ratio of shots taken and hits.
Two modes are offered to run the simulation:
* The SINGLE VOLLEY – STATIC PATTERN MODEL is essentially designed around the errors caused by round-to-round variations and is suitable for most analysis.
It’s also the faster to process and is less sensitive to the total shots count, despite the fact that the larger the number, the better.
* On the other hand, the MULTIPLE VOLLEYS – CYCLIC PATTERN MODEL is designed to deal with both, the round-to-round variations and the occasion-to-occasion variations.
