There is a bit more info on a few weapons in the old 2nd ed wargear books and in the Uplifting Primer and Munitorum Manual. However as noted above why pin down exactly how magic future tech actually works when it could come back and bite you in future writing. Much better to leave the mechanics vague and the effects awesome

It's cool to speculate on the equivalencies to real world weaponry though. Or at least, I'm finding it interesting to read.
