    These checks look and perform just like the more expensive Lyman and Hornady checks, but for a lot less money. Fit and finish were excellent.

    Very pleased with the product. They fitted my Lee mould bullets very well and the service from Sages was excellent which is more than I can say for English customs.
    3 days from Sages to England, 10 days from Heathrow to Devon

    The gas checks are concentric to.001 . They are consistent thickness to+-.002 , and my Ohas triple beam can't measure a difference in them. These gas checks work well on my 300BLK 180gr soft cast lead pushing them to 1150fps. With no leading.
