this seems a bit controversial, my 2 cents is. From talking to HBC the meplats make almost no difference to the performance, the biggest issues are the physical centre of the bullet V its centre of gravity and ogive.

So when the bullet is traveling down the barrel its forced to spin around its physical centre line but when it leaves the barrel that transitions to it spinning around its centre of mass line.

The next issue is the ogive and selecting that effects the BC a lot. Nosslers for instance use a tangent ogive and HBCs a secant (I think thats the right way around and spelling!), this translates to 100fps+ more terminal velocity at 1000yds for the HBC on the same charge v Nossler. Or in another way 1 grain more of 2208 is needed to drive a 308w Nossler than a HBC and keep is supersonic. ie 45grain 2208 for HBC and 46gr (or more for the Nossler). 46+ is compressed (especially on competition bullets I think) and the chambers and primers are starting to sulk at that load, brass life is also degrading as the stress is higher.

Horses for courses. On top of this boat tails are cheaper to make and for short (hunting) ranges the advantage seems to be mute. So if you can cast your own bullets or like this make your own flat bases bullets it can be cheaper and cause less bore wear.

Personally I think there is a lot of marketing hype and crap out there in circulation of the gun world, some of it could actually be against us shooters best interests. So the voyage of figuring it out for myself and only listening to ppl I trust continues.
