Hey, so i like the idea of limited ammo and such for the marines and i was wondering if anyone else had done this and what ammo rations worked for you, i was thinking 3 Bolter Clips, 5 Bolt pistol Clips and i figure that backpacks can only carry the one load. Let me know what ya think or if there are rules for limited ammo i did not see.

There's a good deal of discussion on that in the Standard Kit thread here .

Cool, thank you very much!

I would recommend that most SMs would carry more Bolter (primary weapon) ammunition than Bolt Pistol (secondary weapon). Assault Marines and those lacking a primary ranged weapon are the obvious exceptions.
