For plated look at Berry's or Ranier bullets. I think they're also available through Graf's, MidwayUSA, or Wideners. Good bullets for range time but they don't cost a whole lot less than jacketed bullets.
Don't "stock up for sd" until you've found a good round that is 100% reliable in your gun. This means testing several hundred rounds through the gun at the range and it can get expensive in a hurry. If you tell us what you're shooting someone can let you know what works in their gun. That doesn't guarantee it will work in yours but it's a good place to start. Once you've found a round that works stick with it. It's not worth the cost for re-testing the next wonder round that comes out, IMHO.
