New Features: We have recently added the ability to generate printable range data cards. Notice: This website is totally free.  Registration is only required to protect one person’s data from being modified by another.  We will not send you any unsolicited e-mail. If you would like a feature added to this website, or would just like to comment, please contact us If you would like to contribute any articles related to ballistics or reloading, we would greatly appreciate it. This site is designed for the reloader or serious shooting sportsman who is interested in the ballistics behind the loads being developed.  On this site, you will be able to compare weapons, cartridges, targets, and atmospheric conditions.  As many as 8 loads can be compared graphically at any one time.  Changes can be made to existing loads, or new loads can be created and saved for later retrieval. To begin using this site, selecting “Open Load” from the menu bar will display a list of loads currently saved on the website.  Anyone can view these loads, and registered users have the added benefits of adding and maintaining their own loads. Each load displays rifle manufacturer and model, cartridge, bullet manufacturer and model, bullet weight, ballistics coefficient, powder type and powder weight.  The load table can be sorted on any column, and the loads returned can be optionally limited to your loads or those of other user’s.  Clicking the open link to the left of any load will open the details page for editing and ballistics calculations, and comparison. Return to the Open Loads page and open each load you would like to compare.  Each time a new load is opened, its data will be added to the graphs along with the previously opened loads data.  At any time, the graphs can be cleared to begin a new comparison. Some of the websites most powerful features come from the flexibility with which calculated data can be displayed.  A bullet can be tracked to any distance, and the data can be viewed at any intervals across that distance.  Taking this to extremes, a bullets path of flight can be displayed in chart or graph form, with data points at every yard from the muzzle until the bullet reaches its target or drops enough to strike the ground. Additionally a target can be at any angle above or below the shooter, useful when hunting in mountainous terrain.  The target kill zone can be of any size, and the target can be moving at any given speed.
