Final update on first strike
The report concludes first strike are frangible as defined in law, and are therefore paintball guns firing fs are legal in the U.K.

This doesn't mean other shaped rounds are frangible etc. (eg the one2one rounds that were out for a bit), and it doesn't mean all sites will let you use fs
It does mean that the ukpsf recognises fs, that there is valid testing in place to legitimize them, and that they will be usable again in more places
It's up to individuals sites and event organizers to decide if they will allow them to be used based on their insurance, suitability to the venue etc
Remember that if mixing both paintballs & fs (wg combined magazine and hopper) that fs fly faster and your paintballs will need to be at a lower velocity to keep your fs within the maximum velocity
If you're hit by a fs, it's maintained its velocity for longer so they aren't necessarily shooting hot because it comes faster
