Lead appears to be a fairly unpredictable bullet material with regard to hollow points. Or at least fairly difficult to get a proper alloy.
Make the bullet a little too hard and it won't expand or will crumble and break apart. Make the bullet a little too soft and it'll expand too quickly with shallow penetration or mushroom so much it peels apart.
As posted, my personal 255gr cast reload does very well in gel. It opens nicely and penetrates well when loaded with Unique or 2400. But I tried a LSWC bullet from another source that doesn't do so well. At standard 44 Special speeds of 750-800 fps the bullet will icepick the gel block. Bumping velocity up makes the bullet shatter and fragment within the first 8-10 inches.
I also wonder about cast bullet effectiveness against barriers other than clothing. Will a cast bullet defeat auto glass or automotive sheet metal? I guess I need to visit the local junk yard and see if I can buy a few old doors and windshields.
