umm custom bomb??

can someone make a custom bomb for me? heres what i need it to be like:

bomb no1 : -explodes when touched and shot only
-looks like a solid steel ball
-prop spawner friendly

bomb no2 : -explodes when dropped and shot only
-looks like a jdam bomb
-prop spawner friendly

i need it cuz i wanna build a bomber but none of the currently available bombs explodes when dropped(or touched). i know that i can make these bombs with wiremod, but the fuckin’ reality is that i dont know how to use wiremod. and im too lazy to learn how(i know, im a noob). and uh… thanks in advance!
