You can already, with nothing better than 1920-technology, make an 7,62 mm (.30 cal) armor-piercing explosive round. Sure, the explosion isn't big, but its enough to cause a world of hurt to flesh anyway. You really can't compare what modern special issue ammunition is capable of with 40K bolter-technology anyway for several reasons:
- Modern world has pretty much stoppped developing and producing high-explosive rounds of less than 20mm cailber because they are forbidden under Geneva conventions. Thus we have very limited knowledge of what could be developed if boatloads of money was thrown at it first.
- Bolt is not a bullet. It is a rocket. Thus the outer and inner ballistic properties dealing with how it must be constructed and what it can do are very different. Of those modern world had even less experience than of small-caliber explosive rounds since gyrojet weapons remain just a curiosity and no large scale development of them has been done in recent years.
- 40K explosives may, on the surface, look like modern ones but they are not. No way. Chemical research of the modern day moves much too fast to think that Dark Age of Science people used stuff like RDX. Hell, even by modern standards RDX is an outdated explosive (developed in 19th century) and it is widespread mostly because it is a nice compromise between effectivity, density, stability and production costs. RDX certainly pales in comparison to stuff like Octanitrocubane or DDF which are 50% more powerfull. It would probably be a very poor candidate for small-caliber explosive rounds if such thing ever received enough funding to be properly developed.
