Too soon to make this move and a question.

[Bluff1]

Sng at Stars blinds are 75/150
Late mp limps and it’s folded to me on the button. I have T1000 and As Jc and move in. I figured with T375 in the pot that it was worth moving in AJ. Sadly, the idiot small blind called me with 44 and I got no helped and was busted out. Does anyone else make this move here? I’m also a little confused on one thing about trnys and that is at what point is the blind % of your stack when you move in with any hand? Is it 10% or what?
