ABSTRACT:
An apparatus and method for measuring ballistics in a firearm is disclosed. The apparatus comprises (a) a device for measuring pressure in a firearm-firing-chamber disposed at least in part at the strain sensitive region, and for producing analog signals indicative of the pressure, and connected to digitizing circuits which record the amplitudes of the signals representing pressure as a function of time; (b) a plurality of muzzle bullet sensors for measuring the relative times at which the bullet passes the plane of each sensor and for producing analog signals indicative of these times, the analog signals being converted to digital signals and connected to digital timing circuits; and (c) an acoustic target located downrange and including (i) sensors arrayed at corners of a triangle for sensing acoustic energy emitted by a passing bullet and (ii) a device for generating analog signals representative of the acoustic energy sensed at the triangle corners. The pressure in the firing chamber is measured according to the formula: ##EQU1## and where
