  Compression projectile \Com*pres"sion pro*jec"tile\
     A projectile constructed so as to take the grooves of a rifle
     by means of a soft copper band firmly attached near its base
     or, formerly, by means of an envelope of soft metal. In small
     arms the modern projectile, having a soft core and harder
     jacket, is subjected to compression throughout the entire
     cylindrical part.
