Hornady lock-N-load Classic Reloading press Upgrade Primer Catcher Now catching the spent primers with this device will mean lot less mess dealing with the old primers and trays! You will probably love it so much you will throw away your old original primer tray! Primers simply go down your ram and hit the director (included) then fall into the catcher and 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 and load Classic press only. The Hornady 00-7 version is my store also. Very easy to clip on design. NOTE: PRESS AND CLEAR TUBE NOT INCLUDED Note: Made with 3d printer so may have some small imperfections, but overall looks great P.S. If you don't want to wait on the auction to end, you can buy it now in my store. Other model primer catcher available in my store (click logo by my user name) Thanks for looking
