Eynsford should work fine, but is significantly more expensive than Goex or Schutzen, or Graff (current Goex, used to be Schutzen) if you can get it. If you're going through a pound or two a year it's not an issue, but I go through a can in a week or ten days during the summer, and I find that Schtuzen, Goex, and Kik (when it was available) all worked fine for shotgun (I've connect on a website with people who swear by skirmish powder for shotgun). For match shooting with a rifle, I would go right to Swiss or Eynsford.
