I used it for quite a while for high volume but then had a couple cases get stuck from a military rifle with large chamber and stopped using it. For the most part it worked OK but I often seemed to be on the ragged edge or not enough lube and sizing force was higher than other lubes. For case forming or tough ones like that military rifle I have always used Imperial. I now use regular Pam for high volume loading. A little goes a long way and it is easy to wash off the cases. I use a wet tumbling method so washing and drying cases is not a big deal for me.
