I think I know how to do it. At the beginning I was like you. I didn't know what to do, But I realized that I had 1 kill towards bringing the boom challenge. I said well, I didn't do it with the claymore because I haven't reached level 53, neither the bouncy bettey because I don't have it. Since I have elite membership, there it says in the are of improve some tips regarding almost everything. Basically, they said you can do the challenge throwing grenades and killing enemy members and using claymore and bouncing betty and of course using quick draw pro. I threw some grenades yesterday and my killings were from 1 to 6 in the bringin the boom challenge with grenades, but you can do it also with claymores and bouncy betty. Thanks God I got something for this because I was also crazy about this challenge. Good luck
