Hello! It’s a erotic thriller (B movie). I dont remember the whole plot (was a kid). As I remember a lead actor was Terry Lester (Mason from Santa Barbara), but could’t find movie in his filmography. It’s about some kind of new weapon or bullet for automatic rifles. And of course lots of naked women XD
Looker (1981)?
Young Albert Finney looks a bit iike Terry Lester.
I don’t remember how much nudity there was, but a naked Susan Dey was a bit of a shock.

In case it helps, Lane Davies also played Mason on Santa Barbara. Maybe it was him instead of Terry Lester?
