1) Space Marines are not twice the size of Guardsman. Guardsman's height would be around 5'10" to 6 feet tall. A space Marine is, as I recall, 7 or 9 feet tall depending on where you look. Unless your math teacher was the same as your english teacher, I don't see twice the height that you claim.
Size does not equal height. If a Marine is some 30-50% taller than ordinary humans, as you yourself state, this would lead to an approximate doubling in volume, depending on exactly how precise you are with your calculations and the methods you use for approximating shape. Close enough, in the context here, to talk about a doubling of size anyway. Also, the marine
models are not half as tall again as Imperial Guard
models, not even a third again as tall. Now, remember marines are quoted as 7-9
ft tall, the variety will come from differences between chapter and whether you are talking about in or out of armour. Humans, living under difficult circumstances and recruited from either harsh hive worlds or harsh semi-feral worlds are probably not going to have the best diet, so 5'10" to 6' is probably an overestimate anyway. This makes you further wonder about the discrepancy.
And that comes from a science teacher who also teaches maths and used to teach English as a foreign language.
All any of this proves is that we are playing a game with plastic and metal soldiers and it is not worth getting worked up about.
2) A Space Marine's ammo isn't a bullet. It is a rocket-propelled miniature nuclear warhead... Hmmm... Hot light or nuclear explosion? You do the math. Oh wait... scratch that.
He said "rocket", not nuclear bomb, to be fair. I am pretty certain that the original Rogue Trader described bolter rounds in such a way. It definitely says it here:

In some ways, I completely agree with you though. This is a very ambitious project. If he is going to put enough effort in to do a worthwhile job on the conversions (and it will have to be a LOT of work), then a custom codex would be small cheddar by comparison. The look of the army will either be awesome or crap though, with not much chance of a middle ground).
