50 years ago, there were few, if any, good bullets in 243 for deer, IMHO. They either didn't expand or they expanded in a tremendous fashion. There probably were bullets that worked. I just got tired of trying. Today, it seems there are many options.
I always like partitions as they've never failed me. However, I think that most all of the bullets that were recommended would work.
I've had Gamekings fail by lack of penetration, but that was decades ago. Maybe they are OK now...
They were still erratic probably 10 years ago when I finally quit gamekings.. I"ll use matchkings without a worry though..
