duce accuracy.The use of .38 Special cases cancause problems with loads intended toproduce maximum velocity. Bullets canbe seated ahead '/Io" to produce powderspace in .38 cases equal to the .357. H'tiwever,this reduces bulletlcase contact andgenerally interferes with a proper crimp.The result is reduced bullet pull, andoften wider variations in bullet pull. Theresult is less velocity and less consistentvelocity than can be obtained in fulllength.357 cases.Generally speaking, then, .38 Specialcases are perfectly safe in .357 revolvers,but often are less efficient and may be lessaccurate. However, this doesn't at all precludetheir use for any but the most potentand most exacting uses.TARGET LOADSTypical cast lead lubricated bullets.
