I've not had any problems with the 200gr BT or the 210gr Partition if I put them where they are supposed to go. If you have a good bunch on hand I'd suggest upping the fps a bit and/or just shoot them in the shoulder. They are a pretty tough bullet, but I got good expansion on them even on doe pronghorn. I've yet to shoot anything with them smaller than an elk that required a bloodtrail. All were within feet of where I hit them.
I'm running them at an estimated 2950fps with 65gr R15.
FWIW, and I know my sample size isn't huge but I can tell a lick of difference in the performance of the 200gr BT and the 210gr Partition. Interestingly enough, I've never caught a BT, but have caught 2 Partitions. One in an elk and one in a doe pronghorn...
