you are missing something, the 80-100gr .243 bullets are designed for big game. the 110gr 30 cals are thin jacketed varmint bullets that will not reliably penetrate bone. there is alot more to consider than just bullet weight.

as another note, the "expensive" stuff for the 270WSM is designed for animals heavier than whitetail, so unless your lucky you may not get much or any expansion from the bullet. proper bullet, put in the proper place , my 270WSM has killed 6 deer so far and not one has traveled more than 20yds.
