Need advice designing a fair ultra tech gun.

Certainly as GM you can make up armor-piercing fragmentation if you want to. I don't think it makes any sense at all as an actual thing, nor is it present in any GURPS book I'm aware of, but it's trivial enough to put into the game if you're set on it.

I'm not sure that HEAT/HEMP would be any good for punching boreholes in rock to plant charges. It'll punch holes, sure, but it does so by punching a fluid, very fast stream of metal in. When shot into a rock wall where it can't punch out the far side, I'd expect the hole to be substantially blocked with the penetrator material.

Also, 3d(2) isn't going to get you far into rock. 6d of penetration is going to give you maybe a couple inches into stone. Not more, and possibly rather less since penetrating into a surface with unlimited rock behind it is likely harder than penetrating through a barrier.
