Am I reading this right? You're putting the grains right into the pot to steep then straining them when pouring into another pot? If I'm reading right all I can say is why are you doing this the difficult way? I put my grains into a fine mesh straining bag like those sold on NorthernBrewer and Midwest. This one exactly:
I steep in my main brew kettle so when I'm done I simply remove the bag with grains, fill my brew kettle to the level I'm going to start the boil and that's it. No straining, no dumping the proto-wort into another kettle etc. Less cleanup too.
Also, with the stainless steel strainer remember the absorbed water will add a lot of weight so it won't hold 3lbs of grain weight, not at all. I have that very strainer as that is what I use to strain when going from kettle to fermenter (to remove the hop pellet sludge) and it's works great but it is
a flimsy strainer that can't hold a lot of weight from the handle.
If I'm reading you wrong and misunderstanding then I apologize.
