The Hydro does have a poor flight form. That is a ballistic fact. As for most shooting, who cares, since it takes place at shorter ranges than those where the poor form makes for noticeable degradation in performance.

No one has as yet made a better big bore cast bullet than the .458 caliber 402 grain {wheelweights} Lee Hollow Point. Front HP explodes and sheds and leaves a 300+ grain shaft to penetrate deeply. Just like a Nosler Partition.

Too bad they don't make it anymore. Nothing is like it.

I can only imagine a 550-600 grain version for the .450-class Nitro guns where the bullet could be started at 1700+ fps. An expanding bullet with near FMJ penetration. Good bloodletting near impact and a hole on the other side of whatever walks. You Africans and Aussies shooting all that heavy game would put poor Woodleigh out of business as you'd roll all your own for darn near free...
