Shooting Ballistics Software, Chronographs & Ammo Pressure Testing System

Recreational Software, Inc. was incorporated in the state of Arizona in 1995 to create and distribute specialized products for shooters.  In 2003 we added specialized hardware instrumentation to our product offerings. Our ballistics software, chronographs and barrel pressure testing software are now used throughout the world by serious shooters, industry, the military and government agencies.

RSI Shooting Lab 4.7.6

Shooting Lab ScreenVersion 4.7.6 of Shooting Lab supports custom text scaling on high def. screens. First released in 1998, Shooting Lab has become the standard to which other shooting software is often compared. It is fully Windows 8/10 compliant and will run on Windows XP SP2 or newer. Recent releases even support Lapua .drg Doppler Radar files.

Shooting Lab will more accurately model trajectories to long ranges, estimates bullet drag and gyroscopic stability, keeps load and firearm records, analyzes targets, load density, prints blank targets, box labels and more. It contains everything we believe can be squeezed into software without specialized instrumentation.

Shooting Lab should not be confused with simplistic products for smart phones and tablets. It is a comprehensive feature rich product that reflects 16 years of constant development and input from thousands of users.

Bluetooth Wireless PressureTrace II

PressureTrace II SystemPressureTrace II ModuleThe Shooting Lab program does not forecast pressure and velocity using mathematical models. It is our firm belief pressure cannot be predicted. There are simply too many variables unique to each firearm and a "theoretical" peak pressure has little value for optimizing loads.

Theoretical models of what pressure or velocity "should" be can be interesting but do not help shooters isolate the cause of shot to shot variation in "the real world". PressureTrace shows the affect of neck tension, distance off lands, bore fouling, etc. and was the first product to incorporate Long's Optimum Barrel Timing (OBT) "barrel harmonic" calculations ... for each shot!

The pressure below was captured with our PressureTrace system. The hot high power club load tested as 63,000 PSI at a leading SAAMI laboratory but when shot through an extremely worn barrel, pressure actually reaches 120,000 PSI near the muzzle! It is doubtful the high pressure occurred at the lab in their tight test barrel, but these secondary events are more common than you may think. (See end of this Tech. Article for more information.)

Secondary Pressure
Best of all, RSI's products are affordable and can be purchased as individual components for use with equipment you already own. Feel free to try the software on this web site to learn how instrumentation can help improve your loads, reduce the time required to find optimum loads, diagnose problems and more.

With the complete RSI Lab System you will be able to measure velocity deviations, calculate ballistic coefficients for bullets shot from your rifle and see pressure curve variations in "real time" right on your PC.

Detailed information about these and other products, software, technical articles and other items of interest can be found in the menus at the top of these pages.



CED M2A good chronograph is a necessary part of any ballistics lab. For decades, serious enthusiasts and handloaders have known a good chronograph is the first piece of instrumentation one should acquire. Optimum accuracy simply cannot be achieved without consistent velocity and shot to shot variations cannot be predicted by mathematical algorithms or load manuals.

The CED M2 Optical System

Proven optical technology used for decades that will work with any firearm. The CED 's large display can be read at 100 yards through a target or spotting scope for calculating Ballistic Coefficients with the RSI Shooting Lab software. No one else offers an optical chronograph with large display, optional IR light kit, USB connectivity, 1000 shot non-volatile memory, sensors that self-adjust for available light and voice chip technology. There are many optical chronograph brands ranging from $90 to $900. None match the features, options and overall value of the $200.00 CED M2 Chronograph.

The Labradar Doppler System

  Doppler Radar

The long awaited Labradar Doppler system is beginning to ship. We took delivery of SN 000006 on 10/29 and immediately begin an intensive evaluation of the product. We have already concluded it is a surprisingly sophisticated fairly priced product that a segment of the market will find useful; . . . but with some limitations. Optical chronographs will continue to hold majority market share. A full report will be forthcoming.

What range performance is claimed by Labradar?
Labradar claims seem about right so far. They state it will typically measure velocity of a 7.62 mm FLAT BASED projectile from muzzle up to 100 yards. Testing of a variety of calibers achieved these results. .177 Pellet - 30 yards; .177 BB - 30 yards; 22 LR - 60 yards; 223 - 60 yards; 270 - 70 yards; 308 - 80 to 100 yards; 9mm - 130 yards; 40 S&W - 130 yards; 45 ACP - 130 yards; 500 S&W - 130 yards; 12 gauge Slug - 90 yards; Paint Ball - 50 yards; Arrows - 50 yards. Accuracy of the data is TBD.

Our Observations: The range must be clear of obstructions, brush, etc. Impact berms must be beyond the setting for furthest range velocity to be captured. The radar does not actually capture muzzle velocity because the bullet is fired at the side of the doppler beam. The bullet may not enter the beam for 15 to 20 yards so muzzle blast is used as an acoustic trigger to get a start time, then velocity is extrapolated backward to the muzzle from velocity erosion captured at intervals of a yard or less down range after it enters the doppler beam. Since the tracking data collected for shots is time based, not distance it is difficult to sync Labradar with conventional optical chronographs. So far, it seems to work if one is careful about alignment with the target and offset from the side of the Labradar. Stay tuned.
