I stopped using it because my fingers don't like to work well with adding it. I just changed the powder type to fill the case more so I did not have to use it. But it really works. I had some extremely accurate loads for my 308win but I HAD to use the dacron. Otherwise it was click............bang. And no one here has even brought up temp. I also had loads that were perfectly fine in 70*+ temps. But use that same load below 50* and it was a click..........bang. That was what led me to the dacron by talking with Larry about what was going on.
