If somebody wants to make the most out of their 6mm around here, I point them to the Partition or the TTSX. At least there's good odds you'll have two holes in the deer unless the shot angle is really harsh. The ones we've had to do a lot of tracking with were Gamekings and Core-Lokts, as they didn't regularly punch out on angling shots. I never caught a Partition from my 6mm days, but I have generally seen easier tracking jobs when bumping up to the 6.5mm-.30 cal offerings.
