I think maybe we have already knocked heads on this by email, but if not, definitely get the LFN, in whatever weight you can get 1800 fps from jacketed with. The cast will slip out a lot easier, which means velocity will probably be on the order of 150 fps faster than jacketed, and you'll be in your 1900-2000 fps comfort zone.
If the neck is real short like the 357 Bain and Davis, you better make a throat slug so we don't get the bullet so long it won't chamber without putting the bullet base down into the powder room. Or, throat the thing so it will handle the weight you want.
