I've been tinkering on some loads for my Triumph, been shooting SW's, SST'S, and XTP's with the supplied sabots. For you guys that do alot of shooting, where is the best/cheapest place to buy in bulk? Any good places online, etc..I know it's cheaper to buy the rounds and sabots in bulk, just purchased some Harvestor sabots to try.

I'm especially interested in the SpeerGold Dot and Hornady XTP's, also what has worked well for y'all?
