After this box is gone, I'd get some .451" 230 grain XTPs. They're a little more commonly used in the .45ACP. I use them with bullseye or power pistol, but W231 should be doable too. They also make a 200 and a 185 grain, both with about the same profile. I like the 230s myself, but I shot up a box of lighter ones when bullets were really hard to come by.
The rule is .451 jacketed/.452 cast lead for the ACP. The slightly bigger bullets are generally used in the .45 Colt, but as you can see, there are some folks who use them in autos too.
Good luck!
