While looking over the CastBullet.com reload section dealing with WC820, [http://www.castbullet.com/reload/wc820.htm], there was a caution about that particular powder and the Lee Auto Disk powder measure due to powder leakage. The author decided to ignore the problem, but if I was to use this with my Pro 1000, the powder leakage could gum up the primer feeder, causing all kinds of mischief.
I had to use all the bad words I knew to help me work the kinks out of the new Pro 1000 with 2400 powder falling into the primer feeder. I think that there was a coating of light oil on the Adjustable Charge Bar, and powder would stick to it and then fell into the primer feeder. Once it got cleared up and the primer feeder got cleaned out, everything was fine.
Last week I had two squib loads that got by my obviously faulty troubleshooting methods. Lucky for me, the primer didn't send the (358156) boolit much past the end of the case, so I couldn't chamber another round and ruin the barrel.
So, if I'm going to buy 8 - 16 pounds of this stuff and it will leak all over the place, am I going to have to forget about using it with the Pro 1000? Stan
