OK so I was on a BASC course recently and was told that UK law says I can use a sub .240 calibre for roe etc provided it achieves 1700 ft/lbs as the law states "a projectile of no less than .240 diameter OR achieving 1700 ft/lbs" (according to the lecturer anyway).
Has anyone heard of this or had any experience?
