What would you say are the strengths of the founding chapters and their successors?
The Ultramarines follow Guilliman fairly closely with a strength of around 1'000, but most other chapters didn't agree (but weren't in a position to object, as they were either decimated, missing their Primarch or had peed off too many others to carry much weight, you know who you are Russ), so what are the strenths of the other chapters (roughly) today (non codex primarily)?
