Please let's no fall out over this. Until I get time to do the research here it is from memory. In the early 1990s there was an EU directive that was much discussed in the UKicon shooting press. The UK Government dealt with it by a blanket derogation (is the the word?) which led to us getting two entries for each calibre of ammunition in our FACs - one regular and one for expanding.

In the 1997 ACT the government moved all ammunition and projectiles "designed or adapted to expand" into Section 5 with the exception for hunting.

Soft-point IS designed to expand, that's why we use it, as is some hollow point. However some hollow-point target projectiles have hollow point from the manufacturing process, that is to say: they are not " designed to expand" and so we can use them - and I do. BTW these last points have been back of forth with the HO and ACPO and the above is where we are in the UK today.
