No reason a 243 or 6mm won't work on deer, main issue is operator error.
I have used 80, 85 and 100 grain Sierras, 95 grain Nosler Partitions, 87 grain Hornady BTHPand 100 grain Hornadys with complete satisfaction.
If hit right I cannot tell a dimes bit of difference with any of the above mentioned bullets. Have never had any issue killing deer with these bullets.
Not like an animal that is 250# on the heavy end takes much to kill.

The last time that bear ate a lawyer he had the runs for 33 days!
