?Revelation!

Referral to the relevant ballistic tables reveals only a 1.25 inch difference in trajectory at 200 yds with a 100yd zero for the 500/416 vs the 450/400. All this comes with much more blast ,recoil, and with the animals unable to tell the difference.

Looks like the 450/400 wins vs the 500/416, both up close and out at distance. It has less recoil and will be lighter to carry as well.
