Barnes 195 grain ExpanderMZ
Yeppers, there is not a better performing mass made 40cal bullet for the 45cals.
Now if the OP is not shooting them too fast, a 40/200gr XTP is a great bullet for a 45cal ML. I never had a problem with the 200gr SST expanding but i use 110gr of Blackhorn or more when hunting. They are devastating at smokeless speeds too.
