Here are some options if you want to play with cast hollow points.
I've tried a 185gr LSWC hollow point from another company and didn't have very good luck with it. It shot okay but either broke apart or failed to expand when fired into Clear Gel. There might be a magic velocity that gives good expansion but I never found it. I haven't tried the 190gr from GT. The alloy might be soft enough that the bullet will mushroom well at 1000-ish FPS.
GT's 220gr worked well for me and might be the bullet I'd chose as a "field load." I didn't have much trouble getting 1,000 FPS out of this bullet with 2400. In gel we normally saw 20+ inches of penetration. The nose of the bullet is such that it sort of opens and expands but doesn't mushroom. Looks sort of like a church bell when recovered.
GT's 255gr worked really well. 7.5gr of Unique gave me 900 FPS from my 3" GP. In gel the bullet gave us 15 inches of penetration and opened up to look about like a silver dollar. It would probably be a great choice for defense if you were inclined to use handloads for that type of thing.
Down side to the GT's is they're a little soft. I had some leading when getting aggressive with my loads.
