It doesn’t take any calculation to realize that a .300 win will deliver higher KE than a .308, at all ranges (assuming constant bullet).

Here is the calculation I used, subject to more forensics. as it could be out some.
1/2 bullet weight x terminal velocity squared divided by the amount of powder (grs) it used to obtain that velocity with that particular cartridge and bullet weight.
I used common heavy for caliber bullets and 26 in. bbls for each cartridge.
Anyway ,it was just an exercise to check a theory I had about smaller cartridges and lighter bullet weights. Apparently some disagree.
