I get bored easily.
I tend to experiment with a variety of bullets and loads, and use the best ones for hunting. In the past 4 years for hunting I have used the .40 cal 200 XTP, 200 Shockwave, 200 SST, 225 grain Powerbelt (.45), 185 grain Lehigh and the .452 250 grain Deep Curl.
Currently I favor the 200 SST and 185 Lehigh, but who knows, that could change next year.
I have also observed with deer that the bullet choice hasn't seemed to matter that much- shot placement has been everything. However, I have strayed away from the XTPs because I was getting bullet fragmentation at high velocities, and it was ruining some of the meat and making it more difficult to process the deer. Still killed the deer pretty dead, though.
