I think the BC of a Hydro is around .20.

The answer would be,would you shoot a deer/whatever with a normal FMJ at 300 yards. Most people would say "no" so why would you do it with a Hydro ?.

No matter what your thoughts most people agree that the Hydro does cause more damage than a standard FMJ.

The Hydro works because it keeps that nose shape. Lead wouldn't hold it's shape so in my opinion it wouldn't work.

That is why Woodliegh are making the Hydro with a stainless steel tip now as well,indestructible.
