Virtually all .30-30 bullets, 170 or 150-grain, are soft enough to expand well and drop deer. I just choose the most accurate load.
My .30-30 is a Marlin 336A in the Ackley Improved, and it really likes both bullets you mentioned. I'd happily use either for deer, or the 160 FTX. I'm just about to try some loads with the Hornady 140; if it's accurate, that would also do well, I'd think.
The one bullet my Marlin shoots poorly (so far) is the Barnes 150.
