Normally use Bisley Practise or Hobbys. Was ordering some other stuff, noticed H&N Excite Econ 2 for a bit over half the price of the aforementioned. At £3.50 thought they were worth a try.
Very impressed, used them in my Webley/Diana 'youth' rifles at 6/10m so far. Groups as good - or better - than the more expensive ones.
