I use SNS Casting Powder Coated Lead bullets for making holes in paper - they're very inexpensive, don't lead up the barrel, and are nice and accurate. For powder, I typically use Red Dot or Bullseye since it's an economical and light shooting load; but for full-house I use either Power Pistol or BE-86.
There IS a slight cost advantage to using lighter bullets, but it's hardly worth it for plinking.
