I use the 158gr SJHP loading for both CCW and HD (I don't hunt with a .357 Magnum). My M66 has a 2 1/2" barrel and my M28 has a 4" barrel. While I don't own a chronograph myself, in nearly every test I've seen the Remington 158gr SJHP and other similar loadings generally run 1100-1150fps from 2-3" barrels.
I, personally, would only consider using the 180gr loading from at least a 4" barrel and preferably an even longer one. The loading is advertised at only 1145fps from an 8 3/8" barrel and I fear that the reduced velocity of a short barrel might make expansion unreliable.
