Seems to be kinda silly. I wanna make holes in paper and kill stuff, not have purdy boolits. Cast, size and lube and I have no leading in 44 Special, 44 Mag and 357 Mag. Gas checks go on the 358 Win.
It's nothing to do with "purdy", the color is an incidental by-product of the coating choice. I suppose being able to push them faster and eliminate leading may be silly, but I'll take it.
I killed stuff with mine last hunting season, and was pretty happy with them.
