The problem is that the stress from 45 acp is very similar to the proof load test used for the Webley's, but way above the long term max fatigue limit. Over time the cylinder will start to crack-- and then kaboom. Depending on the type of 45 acp load the failure point comes somewhere around 1000-15000 rounds, which makes it very unpredictable. The Webley factory rating of 13,200 psi puts the cylinder stress at a point where there is pretty much no limit to the number of rounds it can take.
