Build a bigger hammer and use primers 

These come down with a bang Nick....trust me.....the thought of slipping a small pistol primer in there crossed my mind....very briefly.

A mate of mine ended up in hospital once when the primer auto feed on his Lee press malfunctioned and the whole lot went off....the nurses picked shrapnel out of his face and neck for hours, he was lucky he was wearing glasses.
