I’ve never shot polymer-coated or tipped rounds.
Poly-coated Bullets—polymer coats the entire bullet, creating a number of advantages of shooting or loading by hand. Because they’re coated in polymer, they don’t release as much gas from each round, which helps with indoor shooting. The polymer creates a smooth feed in magazine loaded firearms. And the polymer also reduces residue left in a firearm’s barrel. Sometimes color-coded by use.

Polymer-Tipped—bullets with a plastic or polymer tip that improves aerodynamic stability for hunting or long-range shooting. Other advantages are associated with the tip being forced back into the body of the bullet and aiding with expansion, as well as a more reliable feed in semi-automatic firearms. The concept is simple enough; it can fly like a Full Metal Jacket bullet, but expand like a hollow point. The ability to injection mold these polymer tips has also aided in manufacturing consistency. Made famous in the Nosler “Ballistic Tip” design, polymer-tipped bullets are now being made by many manufacturers for big-game hunting, long-range competition, varmint control, and now even personal defense ammunition.
Several other types are mentioned in the same short paragraph fashion at the link.
