Had trouble with the Lee sizer leaving little rings of Cu putting on hornady GC so I used a 310 last nite, shake in PC, none fell off. baked on H.P. for an hour, used my coat hanger wire 'handles' to lift ~70 145gr off & set in pink hospital 'tub' of H2O. Worked great. Then resized in 309. Handles are a rectangle with a bent 1/2" dogleg to hold the tray.
