Snow is correct to a point. Since the late 1990s +P ammo in the 85 is allowed.
For the 1980s, and I have a 85 CH, +P is not endorsed by Taurus.
Many of us who have 85s made in your Taurus' time frame have used +P rounds in them anyway and had little or no bad effects exhibited in any way.
I can bring forth the links( Plenty of those) if need be.
However most of the Taurus and Rossi owners who have snub revolvers made in the 1980s do use standard pressure rounds only.

Federal makes this.

These are 125 gr. LSWCHP coated with a thin nylon. Very soft lead.
These were practice rounds several decades ago that turned out to be very good self defense rounds. Federal took them off the market a few years back and then returned to producing them in the last year or so. Maybe more.
Mas Ayoob and Marshall & Sanow recorded their actual street use record. It was right behind the 158gr. LSWCHP, +P version for stopping fights.
I bought a case of the standard pressure Nyclads to use in my 85CH and the Taurus 856 Lyte magnesium model.
Fast shot to shot recovery times,lack or recoil, and being user friendly are the reasons I use the Nyclads. That and for cost reasons,too.
Even though Taurus says in it's catalogs and at it's web site that all of their guns,except the 85 magnesium Lyte, are +P rated was started in the 1990s as stated. Anything after that time is +P rated.
If you call Taurus custome service at 1-800-327-3776 they can verify most of what I've told you if not all of it.
That or check things out at

I stay at that gun forum, this one and, try to answer some of the Taurus questions if I can. That or get the person to the links or people who can answer the question.
