I absolutely loath the design for the Lee 2 cavity. If the handles are loose (the recent ones are very sloppy) you have to squirrel around setting them on something flat to close them. With that said I've got two I won't part with, a C430-310 and a C452-300 that are great, they cast to the right size without being so oversized the lube and crimp grooves are gone, I attempeted to replace them both with 6 cavity moulds, which were both good quality that cast beautiful but were too big, when I sized the crimp grooves were gone.
So I fight with them as they are good shooter.
The one good thing about the Lee 2 holers though is they are so small you can stick the corner in a melt for 30-60 seconds are start pouring right away as they heat up so quick, I never heat up the pot just to cast with these, just run them 50 at a time or so when I'm doing a run of another boolit.
