BTW, that must have taken some time to post all that data - good job. And how you got the data for the .223 over 200yds is beyond me as Remington stopped there. Again, good job.

The data is from a excel spreadsheet.
Everything you said I agree with. Vietnam etc. Today's fight is at 300 to 1000 yards and the troops need a little more energy at impact.
The new 6.8mm round about to be adopted by the military is the old 30 30 round only a little shorter and without a shoulder for magizine loading.
I use a Horus scope for gorilla's and the supplier of the scope says they are using them in Iraq with kills up to 1550 meters. These are great scopes for distances over 300 yards.
Many gorillas over 500 yards working on 1000 yards. longest today is 822yardds.
BTW, do you know if a Sharps 45-70 is good for Gorilla? I'd assume so - at least to a 1000 yards. Or would that be over-kill?
