Polymer bullets

Any experience with polymer bullets?

The only ones I've ever had were the plastic wadcutters Speer used to make for firing by primer-only through a revolver. Polymers are, in general, too low in density to fly very far or penetrate very well.

If, instead, you meant polymer-tipped or polymer-coated (H&N pistol bullets, for example) or lead that has a polymer powder coat application, you'll need to specify it.

If you are looking at the PolyCase bullets, they have copper for mass, bonded in a polymer. Their GRX design takes advantage of the fact a mold is easily made to give you any shape. Will it actually do anything a flat meplat or truncated cone won't do? I'd have to be convinced. A bullet only completes a revolution once in multiple bullet lengths of travel. It's not like a spinning blade being slowly pressed into something, so the idea appears to me to be a large percent hype. Their .380 bullet only weighs 56 grains, so the density is about half that of a same dimension conventional bullet. This may create stability problems in slower twist barrels. I don't have enough information to tell.

There's no such thing as a completely polymer bullet. There are polymer coated bullets and polymer cased ammo though. And rubber bullets for controlling riots.
Spelling and grammar count!

Short answer, no.

But there is at least one manufacturer making polymer/copper bullets. See:

I will try some when I can find some.

I will clarify. These are lead bullets coated with polymer.
