I ordered a 250 Keith SWC for my 44 special. So what does the " PB " mean. Don`t give me any crap about ordering a bullet and not knowing everything about it. You guys recommended it :D

Plain base, square, all lead. Not a bevel base (BB) or gas checked (GC).

PB is "plain base" i.e. not gas checked. For other bullet casters PB differentiates from BB "Bevel Base" where the bullet is beveled at the base to allow easy release from the machine cast mold. plain or flat based bullets usually resist leading a little better than the BB bullets. Gas Checked bullets resist leading the best.
