You can use any shell holder in any brand of press. The caveat to this rule is with the hornady shell holders. If you use any Hornady products that use a cam lock feature, like the case prep center or I believe the case trimmers, you must use hornady or I believe redding shell holders as the hole in the middle is about 1/16" bigger to make there product proprietary to them. With that being said, if you don't ever plan on buying hornady tools, buy the lee and save the money for extra bullets.
