I carry WW Silvertips in my own Bulldog, but I don't realistically expect them to expand much. For non-defense use, I use a Speer swaged 240 SWC handloaded to about 750 fps (just what I get from the Silvertips).
Recoil is a significant issue with these 18-ounce guns, which means that point of impact changes a LOT with change of bullet weight. Mine hits almost a foot low with bullets of 180-grains, about an inch low with 200s and an inch high with 240s (all at ten yards). That's why I avoid using light bullets.
