I shoot the 240 gr XTP in my 44 mag revolvers and the 180 gr in my 10mm pistols.
performance on game has been stellar. as i have said elsewhere on this forum, i have shot dozens of red stag with it at 1290 fps and many russian boar as well. On whitetails I would not get much expansion (but 10-30 yard runs) until i started opening the hollow point to 0.125" and made them .200" deep. Lose 9 grains in that process but have been able to recover a couple of bullets. Beautiful mushrooms with jackets on. Since starting that all have been DRT and wound channels much more pronounced.
240 grains would not have been my choice load for the grizzly bear, but neither would the 44 mag be except for self defense with a 300 Gr XTP.
Like was said earlier, some love them, some hate them, but hey, it makes for a fun discussion and read.
