Here is a documentary about Boyce's pig-skin experiment:

My questions for the group are: (1) was this ever actually submitted to the CCRC? (2) Did these two experiment fail because the rifle wouldn't have got hot enough?
TIA
Here is what the High Court said about it in 2012 in R (on the application of Bamber) v the CCRC
"24. It would, I think, be helpful to add one further matter. Prior to the Commission making its report, the Commissioners were aware from the screening of the television documentary of the evidence of Mr Boyce, to which I have already referred. His conclusion was a conclusion in support of Dr Caruso, but there was no evidence in that television documentary to show how the barrel of the rifle could have been heated sufficiently.
There is, however, a further report that was submitted, after the Commission's decision of 25 April 2012, in which Mr Boyce set out his view as to how the rifle end could have been heated to the necessary temperature. He accepts that multiple firing would not have had sufficient effect on the temperature of the rifle barrel or the silencer. He concludes that the rifle or the silencer had to be heated artificially in order to burn. It was possible to heat a barrel on a hot plate of a cooker to 200 degrees in less than five minutes.
This issue is not dealt with by the Commission, but I think it would be helpful to express a short view. There was in the kitchen an AGA. The mechanism that Mr Boyce suggests must imply the placing of the rifle barrel on a hot plate of the AGA, and by the hot plate of the AGA I mean that part that is normally used for cooking and which when it is not used for cooking can be covered by a lid. An AGA is not constructed so if a gun is leant against it, it will heat the barrel up. As Mr Boyce makes clear, it would have to be on the hot plate. It seems to me that if that further evidence had been before the Commission, although it would be a matter for them, it would seem very improbable that a barrel would have been heated in that way.
So in my judgment it is clear that the evidence of Dr Caruso, on the assumption that it is admissible, would not in the Commission's judgment have been sufficient to pass the test in Pendleton, and I can see no basis upon which their view could be challenged. "
