Hornady lock & load 00-7 Reloading press Upgrade Primer Catcher Now catching the spent primers with this device will mean lot less mess dealing with the old primers & trays! You will probably love it so much you will throw away your old original primer tray! Primers simply go down your ram & hit the director (included) then fall into the catcher & down a tube. The collection tube has been designed to use a half inch I.D. tubing. (Tube Not included, but can be got at any hardware store. This is to save you money on shipping.) This item is designed to fit the Hornady lock & load 00-7 press only. The Hornady Classic version is my ebay store also. Very easy to clip on design. NOTE: PRESS & CLEAR TUBE NOT INCLUDED Note: Made with 3d printer so may have some small imperfections, but overall looks great Hornady Lock & Load/00-7 Reloading Press Upgrade Primer Catcher
