9MM is .355. Is it ok to shoot .356 bullets in a 9MM using load data for the .355 diameter 9MM bullet as long as bullet weights are the same.

  Yes, with the usual caveat to start 10% below the listed load.

  In fact, despite the spec, most manufacturer's 9mm barrels actually mike out to .356.
  
  I think you'll be fine.
  
  Again, smart to start with low loads.

  If you are really concerned slug yor barrel with a chunk of lead or a lead cast bullet (most people that shoot lead with give you one. Then measure it. I bet you'll find out your good to go.

  Getting the round to chamber might be a problem, but if it does chamber, +1 to what the others said.

  Drops right into the chamber and drops right out.
