4.X sounds a little light. When I was using Unique, I shot 6.X with no problems. These days I load lighter, though.
The next thing is to decide what other bullets you might like to shoot and start working loads for them, although .......... the 230 gr RN bullet is what the .45 ACP was designed to shoot.
Maybe you could get the .45 Super recoil spring and start loading for that. Once you start reloading, there's no end to the fun.
