Decided to try some Sovereign 24grm for OT, the guy who sold them to me said they would be thumpy! Anyway I paid no attention to his warning, because I'm a hefty lad with a hefty gun! Jesus wept, not just punchy!!!! If I hadn't known that they were 24grm I would have said they were at least 32grm!!!! OK they are 1550 fps, but my god they kick! As far as kills go, well they are OK but not as good as my usual RC4 red shot or RC4 Champions. I've also got a slab of the 28grm ones, they are not so fast, will try them next week and see what they're like! Has anyone else tried Sovs and what did you think?
