Two suggestions for you:
1. Start casting your own! I cast the 250 grain Keith type LSWC, out of straight wheelweights; sized to .430, and lubed with Javelina Alox. Those bullets shoot wonderfully on top of 8.5 of Unique, and are very, very accurate.
2. I'd also recommend a short barrel (4-6") for these loads. Recoil is actually not too bad, but in a longer barrel (like my 8 3/8" Model 29) there's some serious in-barrel time that will cause them to shoot quite high if the charge is too low.
For a really good, accurate fun load, you could use the 200 grain JHP on the same charge. More velocity and flatter trajectory.
