Just curious...
Given that you have a .243 cal bullet and a .257 cal bullet and that they weigh the same.. 100grs for instance and traveling at virtually the same velocity.
Explain to me then how the 257 cal bullet is a safe bet and perfectly adequate while the 243 bullet is a joke and has no business being used on medium game?

This should be interesting..will get the popcorn goin now. LOL
