In the past I've done all my hunting with traditional C&C bullets but I'd like to give some monos a try this year. I hunt up in NY, which means primarily Whitetail deer and I prefer to take lung shots.
Monos do not kill as quickly, in general, on lung shots, because they don't destroy as much tissue because they don't expand as violently.
For pure lung shots, you'd be hard-pressed to ever beat a C+C. Your best bet with a mono for quick lung shot kills will be the Cutting Edge bullets that blow their petals. If you're using a 30 caliber, the 135 grain Raptor comes highly recommended when driven at high speeds. We have not tried the 125 Maximus but that looks good also.
The other great results we have had (and are using currently due to accuracy and lower price) are the Barnes TTSX black tip 120 grain. This bullet is "softer" as it is designed for the 300 Blackout, but when driven at 308 velocities it still holds together but expands wider than the rest of their line. We like it for more mono destruction even on lung shots. We will probably stick with this bullet until something very different in technology comes along. The 110 black tip works the same but with a lower ballistic coefficient.
