I believe that's because the normal shotgun uses fragmentation rounds, whereas the Marines use solid slugs.
Once upon a time, Marines and Guards used the same type of ammunition. Then the Dark Angels wanted to be special, so their 4th Edition Codex introcuded gave them S4 shotguns together with this piece of fluff:
"Shotguns are sturdy and versatile weapons wielded by warriors across the Imperium. Space Marine Scouts sometimes carry shotguns when they know their mission will involve short-range firefights and fast-moving tactics. The Dark Angels issue their Scouts with special 'Manstopper' shells for use in their combat shotguns. These use a particularly heavy solid cartridge with a massive propellant charge, making it more powerful than a normal solid shot." Then, suddenly these started popping up in the other Chapters as well, and what used to be a Chapter-specific variant got turned into a new sort of standard. An example from the 5E Blood Angels Codex:
"Shotguns are sturdy and versatile weapons often carried by Space Marine Scouts. They are invariably loaded with manstopper shells to provide extra punch." Of course, it kind of sucks for the Guard that the one advantage of
their shotguns is no longer represented in the rules. Back at around 2E, shotguns actually had a Blast Area. Note the different profiles in this scan of the old Wargear book:

They
do use physically bigger guns - it's just that their weapons are actually armoured themselves, so as to better withstand the stress of close quarters battle and stuff like a Marine breaking through a wall or using his bolter as an impromptu hammer to club in some Ork's skull. This makes their weapons more reliable whilst keeping their ammunition compatible with Imperial forces throughout the galaxy, so that they could tap into regimental supplies whenever their own stocks should run low - certainly, that's better than hightailing back to their own homeworld, or having to go
beg another Chapter. I imagine their starships are loaded with ammunition, but simply having the
option to go ask the Guard surely must be a nice thing to have, just on the off-chance that your campaign really does last long enough to empty even a strike cruiser's armoury, or that ship gets destroyed, or an airdrop for resupply is too dangerous due to enemy airpower or
AA capabilities.
The next level of the cal .75 shell is the Heavy Bolter's 1.00 slug, and
considering its size it just strikes me as very impractical to put this into a rifle. As an assault-specced shock trooper, how many shots do you want to get out of your magazine?
(this is another difference I could imagine, by the way - the
3E rulebook mentions bolters having magazines of between 20-30 rounds - I'd imagine that Marine magazines are closer to the 30, whereas a normal human would be closer to the 20)
