Maybe I'm a luddite, maybe I'm just plain old boring, sceptical and cynical, but these lighter lead free pellets I fear will exhibit inferior BCs to our trusted, well-developed lead pellets, and those higher muzzle velocities won't be replicated downrange.

Coupled to the high cost and my (maybe unfounded?) fear of potential damage to our delicate bores, this translates to me never feeling the need to try them out.

If certain types were found to be superior to good, old fashioned lead at some point in the future, and the bore damage fears allayed, I might at that point be prepared to give them a go, but then there would always be the cost issue to consider, especially as I only shoot for pleasure.
