Do you handload your own ammunition and still do not know why one load shoots better than another?
We develop and manufacture BTMS – Ballistic Tuning and Measurement System. With every shot, it simultaneously measures chamber pressure, recoil, and barrel movement. The results are stored in an application that helps you understand the differences between individual loads in practical language — not in laboratory numbers.
Every Handloader Knows This
Two loads, the same components — and yet one shoots differently. Where is the problem? In the powder? The bullet? The case? Without measurement, it is only a guess.
Inconsistent Results
Cartridges from the same batch behave differently. Why? Without data, you cannot tell.
Decisions Based on Feel
Tuning happens by trial and error. Without feedback, we keep going in circles.
Laboratory Measurement Is Not Accessible
Ballistic laboratories exist — but for handloaders, they are neither financially nor operationally accessible.
No Comparative Baseline
Without numbers, two loads cannot be compared objectively. Feeling is not evidence.
From Shot to Clear Evaluation
BTMS is a modular measurement system. You configure it for your cartridges, fire safely — and the results are stored in an application where you can see the differences between loads in practical language.
Modular Setup
Body, barrel module, and cartridge chamber. You configure it precisely for your cartridge types and calibers.
Safe Shot
The experiment is performed by the mechanics — not by a person. The operator and customer are separated from the ammunition being tested.
Simultaneous Measurement
With every shot, BTMS records three quantities at once — in real time, without data loss.
Application and Evaluation
The results go into the application. It shows which load behaved more calmly, more consistently, and more repeatably — without requiring specialist background knowledge.
Four Sensors, One Shot
Every shot = a complete picture of what happened. No guessing, just data.
Chamber Pressure
A piezoelectric sensor records the pressure curve during the shot — the basis for comparing loads and safely tuning the powder charge.
Barrel Movement
A set of three special sensors captures the dynamics of barrel movement — important for precision shooting and result consistency.
Recoil
A set of three special sensors also measures the intensity and course of recoil and muzzle rise — key for evaluating shooting comfort and firearm behavior.
From Shot to Clear Result
BTMS is not just a steel structure with sensors. It is a complete system — device, measurement, application, and clear evaluation in one.
Shot Measurement
BTMS captures the pressure curve, recoil, and barrel movement. Every shot = a complete data record of what happened inside the cartridge.
Load Storage
The application stores the series, a description of the tested cartridge, and shooting notes. You can return to each load even after a long time and see exactly what you tested then.
Clear Evaluation
The application translates the results into practical language. It shows which load behaved more calmly, which had a stronger expression, and which delivered a more stable and repeatable result.
Tools for Precise Tuning
Safe Range Tuning is not a classic shooting e-shop. It is a set of tools for handloaders who want to work with data.
BTMS
Ballistic Tuning and Measurement System. It simultaneously measures chamber pressure, recoil, and barrel movement with every shot. The results are stored in an application — and that helps compare which load behaved more calmly, more consistently, and more repeatably.
- 3 sensors at once — pressure, recoil, movement
- Modular barrel module and cartridge chamber
- Safe operation — mechanics, not a person
- Application for storing and evaluating series
- Certified by ČÚZZS
- Every unit — control shot
- First year of the application included in the startup program
Sizing Die
A simple mechanical tool that, when seating the bullet, unifies neck tension along the full length of the case neck and aligns the projectile with the cartridge axis. It replaces both press-fitting and classic crimping in a single operation.
- Unified bullet hold
- Better projectile concentricity
- Longer case life
- Manufactured for a specific caliber
- Available in standard and hardened versions
We Stand Behind Our Product
We are a startup. We know what that means — and that is why we set the terms so that the risk is on us, not on you.
14-Day Return Even After Use
Try BTMS at the range. If it does not suit you — we will refund the full amount. No questions asked.
Buy-Back Within 5 Months
The buy-back price is fixed in advance and contractually guaranteed.
ČÚZZS Certificate
BTMS is a certified measuring instrument. Every unit undergoes a control shot and proof testing.
Contractual Commitments
SafeRange Technologies s.r.o. — a registered Czech company. Company ID: 24487996. Utility model registered with the Industrial Property Office.
2-Year Warranty
A precisely machined system with a two-year warranty on the entire device.
Made in the Czech Republic
Every unit is manufactured in the Czech Republic. No anonymous production abroad.
Add a Premium Measurement Service to Your Range
BTMS enables your shooting range to offer handloaders a paid ballistic measurement service — repeatedly, without the need to build your own laboratory.
- Attract a new customer segment — handloaders and technical shooters
- Increase the average value of each visit
- Offer a service no other range in the region has
- Payback with only a few customers per week
Indicative Calculation at Medium Utilization
Not Convinced? Come and See.
We organize BTMS demonstrations as part of presentations at shooting ranges. You will see the device in operation, receive live data from shots, and you can ask anything. The number of places for handloaders is limited.

What exactly does BTMS measure and how will I use it?
With every shot, BTMS simultaneously measures chamber pressure, recoil, and barrel movement. The measured values are stored in the application. It shows you the differences between loads — which behaved more calmly, which had a stronger expression, and which produced a more stable result. You do not need specialist background knowledge — the application translates the results into practical language.
Is BTMS a replacement for a ballistic laboratory?
No. BTMS measures differences between loads — not absolute values in laboratory units. Its value lies in showing which load behaved more calmly, more consistently, and more repeatably. Exactly what a handloader at the range needs to know.
Who can buy BTMS?
BTMS can be purchased exclusively with a valid firearms authorization (ZO) under Act No. 90/2024 Coll. During the order process, you will be asked to provide proof of it. Before BTMS is shipped, the validity of the submitted authorization will be checked.
What if BTMS does not suit me?
Return it within 14 days and, if the device is not damaged, you will receive the full purchase price back. This also applies after first use at the range. No questions, no forms. In addition, you have the option of a buy-back within 5 months at a pre-agreed price.
How does the startup price work and why is it so advantageous?
The planned regular price of the system is €2,028.46, but within the startup offer the price is reduced to €1,014.23, i.e. by 50%. This discount applies only to the first 40 units, and once they are sold out, the startup sale will end. The startup offer is advantageous mainly because the customer enters the project at an early stage. This helps finance the start of production and the introduction of the system into practice. As a reward for this trust, the customer receives a price that will not be repeated later. Anyone who orders BTMS in the startup phase gets the same system for half of the planned regular price. The lower price is balanced by the fact that it is an order with deferred delivery in 90 days. After the startup series is sold out, the price will return to the standard level.
How quickly will I receive BTMS?
BTMS is manufactured in the Czech Republic and every unit undergoes a control shot. You will find the current delivery time in the configurator during ordering.
Can BTMS also work as a service at a shooting range?
Yes — and that is its second strong application. A shooting range can offer BTMS as a paid measurement service for handloaders. More information can be found in the section for shooting ranges.
