Ive been playing 5/10 live 9 handed lately and the other day i had a spot were im not sure if my play was optimal.

Im sitting on a 2600 stack and i raise from the dealer with AKJ2 double suited clubs and spades i raise preflop to 50 and get 6 callers; flop comes 9h Ks 3h - they all check back to me and i opt to check to give myself a free card as these players really like to check raise. Turn comes a very good card making the board 9h Ks 3h 4s giving me a backdoor nut flush and gutshot. Big blind who is a very loose player bets 200 into the pot and a middle player calls i reraise to 600 and he reraises all in 2200......and i fold. Do you think my reraise to 600 was a mistake? i was trying to raise my hands value on the pot thinking i had alot of odds to improve my hand for the river considering small two pairs or draws might be in his range and thinking i could bluff alot of rivers pretending i had a set.
