Interior Ballistics
[Inside the Barrel]
Interior ballistics considers the relationships happening while the bullet is in the barrel.  Silhouette Ballistics may estimate muzzle velocity and chamber pressure for different powder charges.  Also estimate the muzzle velocity and chamber pressure for different barrel lengths, different cartridge lengths, and different full case water capacities.  The following example screens are provide to show you briefly what Silhouette Ballistics Interior Ballistics Program looks like and how easy it is to enter data.  The Interior Ballistic Program included with Silhouette Ballistics is very handy for reloading ammunition. 

Interior Ballistic Program Tables


The Interior Ballistic Program will generate tables for different powder charges by weight and list how full the case is in percent.

The Interior Program will also estimate the muzzle velocity and chamber pressure for any given bullet weight. The muzzle velocity and chamber pressures are only estimates based on an ideal powder for the cartridge volume and bullet mass. The Interior Ballistic is useful for determining the affects that small powder charge changes have on muzzle velocity. Tables for different barrel and cartridge lengths may also be generated.

Powder Charge Interior Balistic Table 

This interior ballistic program will identify a suitable burning powder for reloading most cartridges, estimate a load, calculate its hypothetical muzzle velocity and compute the load's hypothetical chamber pressure.  You can also create data tables and graphs by varying the powder charge, overall cartridge length, barrel length, or full case water capacity.  The hypothetical results for the muzzle velocities and chamber pressures may be viewed on screen or printed.
This program can not compensate for powder burning rates.
This program can not determine maximum or minimum loads.
This program can be used to evaluate the relative affect that :
1. different powder charges,
2. different barrel lengths,
3. different cartridge lengths,
4. different full case water capacities,
will have on the hypothetical muzzle velocities and chamber pressures.

Always consult your loading manuals for safe loads.
