RSI's Personal Ballistics
Lab
Components
RSI
Shooting Lab 4.x for Windows
Now
fully VISTA compliant! Our
computer software is the starting point for building
a personal ballistics lab. First released in 1998, Shooting
Lab has become the standard to which other shooting software
is often compared.
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.

New
PressureTrace II - Now Wireless!
The
Shooting Lab program does not forecast pressure
and velocity using mathematical models. It is our firm belief
this can only be done safely and accurately with proper instrumentation.
There are simply too many variables unique to each firearm
and "theoretical" peak pressure has little value.
Theoretical models of what pressure or velocity "should"
be can be interesting but does not help 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 is the first product to incorporate Long's
Optimum Barrel Timing (OBT) "barrel
harmonic" calculations.
The pressure
below was captured with our PressureTrace system. In a test
barrel it correctly tested to 63,000 PSI at HP White, and
Quickload predicted over 60,000 PSI; but when shot through
an extremely worn barrel, pressure actually reaches 120,000
PSI!
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.
The CED
M2 Chronograph
A
good chronograph is a necessary part of any personal ballistics
laboratory. 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 tops,
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.

PRESSURETRACE
II Is Shipping As Production Rolls In! We are scrambling
to have systems built as fast as possible but anticipate occassional
inventory shortages as production ramps up.
The CED M2 Model Chronograph continues to be
in short supply world wide as demand continues to exceed CED's
production. To check our store inventory for all products, click
