I do about the same, but use a nitrile glove on my hand to stand up the bullets. I just make sure there is a little powder on my thumb and forefinger then pick up the bullets to stand them up. No need to mess with tweezers or pliers. It is much faster and much less likely to booger up the coverage than metal implements. I reuse the glove until I tear it or otherwise get tired of messing with it.
I use the nodleneese pliers so I can whack the bullet on the edge of the container and free any excess powder. You can see in my photos that I get a few clumps, but mainly with this red/gold metallic powder which is twice as hard to get right as PBTP light blue or Kawasaki Green.
