John Bowkett told me a long while ago that BSA had requested a pcp pistol and wanted to use some components from the 240 magnum. He worked on this for quite some time producing several prototypes, see the JB Fanpage photos
, butBSA marketing department said there was no market for a pcp pistol and it was shelved.
The polystyrene tray, he said, for the 240 Magnum had a longer than required cut out in front of the muzzle. When asked why he was told that they were going to manufacture a longer, high power version for the US market. That again was shelved but the polystyrene trays had already been ordered so they stayed as they were.
That would have been a nice pistol to use if de-tuned to below our limit and with the extra length to control the jump. I had a 240 Magnum and while it was accurate when mastered it was very hold sensitive..
