Yeah I used these in my old muzzle loader and I got them at Wal-Mart. No complaints from me.

I use the Winchester 209 primers I got from a gun store in my new muzzle loader. I need to get some more as my cleaning stuff spilled all over them and ruined the box. They have still shot fine soo far but not sure I'd trust them for hunting anymore. I may get a new box for hunting and use these just for targets.

How long can you expect caps and primers to last? I have some #11 caps from last year left from the pack I used and then have a full box I bought on sale that I haven't opened. Will they still be good in a year or two?
