I use them in my 410, 28, and 20ga reloads. I know several guys using them in ml. I use Winchester 209. I would use them. If that is only thing i had. I seen a guy on u tube. He paid 27.99 for 100 ct of cheddite. I asked him why. He said that was only thing he could get. And i thought 5.99 a 100 was high. I try to keep 6,000 to 8,000 on hand
