I have next to no 209 primers left and may have to switch over to my musket-cap breech plug and firing pin on my in-line. A local mom-and-pop has Cheddite 209s in stock and I am tempted. I've read there is a slight size difference between the European Cheddites and American 209s, but have read many reports that they work well in in-lines. Does anyone have any first hand experience with Cheddite 209s?

My rifle is a Traditions Pursuit .50.
