For legal limit I would use the best from H & N FTT, JSB Exact and Crosman Accupell. I really wouldn't bother to test any others.

Thanks for all the replies. I'm a bit confused re crosman accupels (tin) and premier (box). These did indeed work well in my ,22 rapid but i didn't think they were still available. Aren't they badged "Webley" now? (which look different to me) or are they still available somewhere?
Thanks
