You're probably thinking 7.65, as, to the best of my knowledge, Beretta never made a 7.63 pistol... that cartridge was exclusive to the "Broomhandle" Mauser and a handful of other weapons made in Germany.
7.65x17 Browning SR (Semi-Rimmed) is also sold as .32 ACP.
763 is an abbreviation used for the Boeing 767-300.
It is a filter that is used for filtering the oil in a Bobcat 763.
The highest factor of 763 is: 763
763-2222 763-2222 763-2222 763-2222
