 No they are effective since they frag. the target at ground-zero,but the 
reason they're not used outside of heavy machine guns and cannon is that 
 they're too damn dangerous to use since if the explosive is loaded into
small arms ammo it cannot include `bore safe' features ,so will explode in
 a hot chamber or if there is any cycling difficulty in a auto. they will 
explode causeing a chain reaction into the mag. injuring the user.

 BTW the occasional wierdo does use explosive packed bullets(see TTBOM for
details of production).

 No it isn't a grenade launcher is an _*indirect*_ fire weapon bullets go
direct.Remember if you pack a revolver bullet with explodives it will prove a
 worth while weapon (I worked out earilier that a .41 mag semi-wadcutter pack
with primary ex. will double its power[I forget the figures] and remember
 the bullet does have to penatract and hit some thing hard to detonate,
that right it explodes in the target or you could put a ball bareing on
 top of the round).
