i have 6 gang lee molds for both 44 and 357/38.tumble lube molds ,we call them.as stated before the lee's take a little more care to produce good bullets,alignment is subjective,they are also more affected by temperature,or affected more quickly at least.
i have shot thousands of rounds of both of these,cast from #2 alloy,liquid alox and shot as cast.we only use them at the range,some guns like them better than others but they shoot fine.those six gang molds will make a pile of bullets in a hurry.
for a range bullet to shoot up with the family or for just everyday plinking i think they are fine,for a hunting or more accurate round i prefer my lyman gc molds.lee molds are hard to beat for the money. besides those molds i have the 480 mold,45/70 hp mold and a 50/.512 cal mold i use for my 50 alaskan,i did have trouble with the 480 bullets while sizing,at first i blamed the mold or alloy.it wasn't either,it was user error,changed my sizing process with help from GBO members they work great now.good luck,adker
