I've reloaded for rifle and wheelgun for a while, but just got into shotgun reloading. I got these to round out my capabilities. MEC products are good quality and cabelas had them all in stock, so that worked out well.
I live out in the sticks and can't get to store often, so on weekends or in the middle of the night when I want or need to load some shells and may need to use some older powder I have on hand and I am out of my regular powder I use for a certin load I go to my old loading books and find a load I can use. If you don't have the proper bushing then you have to weigh out each load or do without.
