Red and green (100 count?) will be the older, softer ones.
Ya - I'd be wary of over-expansion, especially at 300 WSM velocity. I loaded some of the old 165's for a buddy's 300 Win Mag many years ago - results on mule deer were ugly. We switched to a heavier, and stronger bullet. 180's as I recall, and results were much better.
The newer 165 gr Ballistic Tips have been wonderful in both my 30-06 and the 308 as well. Elk, black bear, mule deer & pronghorn, and all were quick kills with excellent bullet performance. The newer ones seem much tougher than the old Ballistic Tips.
