Hi Josh
As Iggy said you must never make your bomb that hard....the whole reason is to create a feeding spot and to keep the fish in that feeding spot for you whole session.
Making you bomb hard just means that the fish will bump it once or twice...nothing happens and he wil move on. Looking for a place where he will get more feed, more often.
Just follow the instructions on the pack or as noted here. Two feed one water, Feed more often and on the same "kol" and see what happens with you tempo and your size of fish.
