I haven't seen them available yet. Airgun Source and Air Gun And Archery Fun would be my two guesses.
Actually quite disappointed with these. My PCP only can get 600fps (they must not seal well) with these and groups @35yrds are over an inch. I'll still with the heavy JSB's @ over 900fps and one hole @ 35yrds.
What are you shooting them with?
The twist rate and choke on a slug barrel is different from a conventional barrel as well. The slugs may be tumbling.
Maybe I should take that extra full turkey choke off then LOL
