Be VERY CAREFUL that you are using the correct data for the Clays variant you are using. The names and labeling can be somewhat confusing.
I have used it for several years for .44 Special loads. Was very happy with it until I bought and started loading from a new bottle that I thought was the same as I had loaded up a large batch of ammo with 8 years ago. In January I took a few of the new batch of ammo that I had loaded Out behind the shop for testing. On the third shot blew the top half of the cylinder and whole top strap off of my Charter Arms Bulldog.

Am changing powders for the next session.
