Quoted:
I read Dr. Fackler's papers and can not remember an instance where ftlbs were an indicator of terminal effectiveness...
I agree.
I was using that as simply illustrative since I don't think gelatin tests at 800 yards have been conducted for either round.
At that range neither projectile would perform as advertised because they are both too slow.
So of the two, with similar profiles and at relativey the same velocity, a heavier larger diameter bullet "should" have better terminal effects based on pure kinematics (larger wound channel, more momentum carries the projectile deeper into the target,etc. - although a larger diameter projectile will have more surface area and thus more drag/resistance as well, so the residual velocity will fall more quickly).
There is a difference between paper and flesh we speaking of "effectiveness".
But I certainly wouldn't be shooting either round at 800 yards hoping for very good terminal effects.
Either way I was attempting to point out (poorly) that selecting different projectiles for comparison needs some consideration.
The VLD seemed like an odd choice for comparison to me.
