Some time ago I posted pictures on here of a BP revolver that one of our club members loaded with nitro. I can't remember all the exact details but he saw the word "universal" on the powder bottle and assumed it would be OK in all guns.

It was very lucky that nobody got hurt when the cylinder blew out. The divisions between the firing points took most of the force but someone stood behind him caught a small piece of shrapnel in the face. Fortunately it didn't do any permanent damage.

As a result, anyone home loading now has to pass a short course and submit loads for evaluation.
