It would help to know what firearm you are planning to use these cast bullets in? For low to medium velocity loads especially in a pistol or revolver Lee makes a push through sizer that is used with Alox that works OK and the least expensive way to get started.
You can often size bullets down .002 to .003 without hurting accuracy too bad. The .365 goes back in the pot something wrong here, maybe the mold wasn't all the way closed or a piece of lead hung up somewhere causing the mold to remain slightly open as you cast. PM me if you like there are some web sites that are devoted entirely to cast bullet shooting.
Good Luck
