i've Just Brought One Of The Speed Feed Collars For My Halo Hopper, The Only Problem Is After Taking The Old Lid Off And Losing The Spring For It 10,000 Times I Found That The Speed Feed Didn't Sit Snugly Against The Rim. The Collar Just Seems To Be Way To Big. Any One Out There Experianced The Same And Could Give Me Some Tips Please As The Collar Feels Like One Long Dive To The Snake And I'd Lose All My Ammo Out The Top.
