T i have a chaos story for you....It's called the Chapter Master Huron and the Baddab War. There is actually  a in canon a rule against allowing SM chapters from stockpiling gene-seed. While it is obviously (as the war itself would show) hard as hell to enforce your not going to get away with stockpiling gene-seed withiout the permission/recognition to go past codex standards. Space wolves do it cuz they say fuck the rules and they've proven themselves, Black Templar do it becouse they have proven themselves and no one cares, Huron Tried it and now he's the pirate lord of the Malestrom.
