So bullet performance on game isn't a factor?
Well considering I've read several reviews here and many reviews elsewhere on how well it works on deer sized game it's performance appears acceptable by all counts as well. Of course performance is a necessary piece of the puzzle for hunters, but there are a lot of range junkies that don't always or never hunt, but like to shoot also.
Simple fact though, higher BC means that the bullet flies flatter than a 405 Rem etc. Thus for a lot of 200 yard hunters, this puts them in a situation, where sighted for 125 yards they always have point blank shooting without having to worry about elevation. If you don't like them, basically don't use them, but there are others who do like them and they fill a niche previously unavailable for .45-70 shooters.
I like my 350gr FP and it does all I need out to 300 yards. So I'll stick with them.
