The coating won't come off. It might leave a mark in your barrel or on your hard target (little teflon smudge) but nothing much.
Except the real exotic BBs, there is no such thing as metal BBs.
And even if there was, it's the weight that matter, not the material.
A metal BB deformation on impact won't make a difference compared to a plastic BB deformation on impact.
