What is your favorite powder horn spout size?
I prefer a 3/8" hole in the spouts of my powder horns,.... this size doesn't take long to fill a 70-100+ grain powder measure, and since all of my horns get refilled (with powder) from the spout-end, 3/8" seems to work good for me.

An old original horn I have, has about a 1/4" hole in the spout, but it's a "small-to-medium size" horn, and I think it was probably originally used with a small caliber rifle of maybe .32-.40 caliber,.... but it too must be filled from the spout end.
Your thoughts and preferences are appreciated.
