I’ve had all the pots, bottom pour. I pour all kind of fishing lures and bullets. A long time ago I decided to get big standard pot and pour with ladles. I figure I make up for the time by not having to fool with bottom pour problems. They all have it from cheap Lees to the top shelf models. A lot of casting problems are caused by one pot guys that melt scrap in their bullet pot. Dross and dirt in bottom pour assembly will plug it up or prevent it from shutting off.
