I encourage you to take a second look at the Barnes 80 grain TTSX. Yes, it is less than 100 grains, but has a 99% weight retention and the higher velocity of the lighter bullet makes up the difference for the energy you need. The TSX has had incidents of failure to open properly on light game and this is one of the reasons Barnes developed the TTSX. The polymer tip ensures good expansion and gives a higher BC. When comparing the BC with other bullets it's important to understand that Barnes calculates their BC at 300 yards rather than the shorter ranges that other manufacturers do. The effect is a more accurate BC for calculating trajectory, but on paper it looks like it's lower than it really is.
Even though it's 80 grains, this bullet's unique design will give you deep penetration with reliable expansion and excellent energy transfer. I have known several people that use this bullet in 243 and 6mm for deer hunting and there's not a single complaint from any of them.
