500-

Sir-
Empiric data and the penetrtion data on the 458 at 1950 fps vs 2180 fps in the few penetration tests I found suggests a marked non linear increase in penetration depth with velocity(~2x depth with 200fps more velocity). Makes sense as Energy/works relationship with the square of velocity

Todays 458's are considered adequate at 2050 fps so maybe the bottom threshold for penetration on Ele is just that-- a modern solid projectile with a S.D.>0.31 moving at 2050 fps.

If so this would rule out the 577/650 gr bullet with a S.D. of 0.28 at 2050 fps for sure!! It would need to be driven MUCH FASTER with solids to get adequate penetration. Thus it would seem to NOT be a good Ele round in ANY Double.

Am I wrong here? What is reality from those who have shot a multitude of elephants? Thanks for your input and your thoughts on the above--

Lastly,I am curious.
Does anyone recall the standard DG Double rounds with the slowest/fastest velocity and a S.D> of 0.31?? Would the 375 Flanged be the fastest?
