Unique loads for Webley Mk I/II ?

[NorthWoods22]

Anyone have any unique loads for Webley Mk I/II with 45 ACP brass and 230gr LRNs?

I've worked up to 5.0gr Unique at 1.275" OAL for a velocity of 570 fps.

Midway USA's load booklet for 45 ACP says this should be at 10,000 psi.
They also say 5.6 gr Unique at 1.275" OAL will get a pressure of 12,500 psi, which should be in Webley's service pressures

Any one have any experience with 45 ACP brass, Unique, and regular 230gr 45 ACP lead bullets?

I have tried the 230 fur aged and was surprised with the accuracy. I didn’t expect the bullet to work well when I loaded some to try. I use 5 grs of Unique. The bullets where previously sized to 0.452 for my 45 acp so should have been under size for the 455. I use modified 45 Colt cases shortened to 0.980. I was using 45 acp dies and decided to taper crimp which works well. My normal bullet is a RCBS 255 gr which I also load with 5 grs of Unique.
