I'm relatively new to in-line muzzleloading. I have a Austin & Halleck 320 which is a real nice shooter. But alas they are going out of business and I am starting to get concerned about parts. I am wondering if anyone can advise if there are any other manufacturers who make a breech plug that would fit. I do not know the thread size of my A&H. It is a 50 ca. I can try (if they still have any) to get one but it would be much simpler if another brand breech plug would fit.
