    First time user of Sage's Gas Checks. Having used Hornady gas checks previously, came across Sage while doing a search. Ordered 1000 copper gas checks and lubed/sized/gas checked up 4 different weights of 30cal cast bullets. Outstanding performance. My cast bullets with Sage's gas checks shot just as accurately as the FMJ/BT bullets did.
    To say I am pleased would be an understatement, will definitely order more. Now that I have my barrel broken in, I will only be shooting cast bullets from now on.

    I also like the idea of helping someone live out the great American Dream of having their own business. Shipping was prompt and fair, a quality product that does what it's intended for, what else could one ask for?

    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.
