This is part of my late husband’s DVDs this one is the RSI shooting lab version 4.4. It is 2000 to 2009 recreational software. It is for windows more than great ballistics program. If you reload it will help reduce group size and organize records if you hunt it will increase your chance of taking a trophy if you compete it will improve your shooting it even prints, blank targets, and ammo box labels no other software delivers as many features in one package.
