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

Now at version 4.7, Shooting Lab includes more new features and enhancements users have asked for. First released in 1998, Shooting Lab has become the standard to which other shooting software is often compared. It is fully Windows 7 compliant and will run on Windows XP SP2 or newer. The latest release supports .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 simple Ext. Bal. products based on 110 year old algorithms or products that are just a PC version of load manuals.

Bluetooth Wireless PressureTrace II

The 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 occured 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.)

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.

The CED M2 Chronograph

A 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 's large display can be read at 100 yards through a target or spotting scope so it is ideal for calculating Ballistic Coefficients with the RSI Shooting Lab software. No one else offers a 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 chronograph brands ranging from $90 to $900. None match the features, options and overall value of the CED M2 Chronograph.
