azrik Posted May 26, 2011 Share Posted May 26, 2011 I've been working up some loads for a new 40SW I've got and before going to the big blue, I use my old rockchucker stuff and RCBS Uniflow powder thrower. So I fill the Uniflow with Titegroup and after doing some different reloads, go to refill and notice the powder is sticking to the side of the reservoir. I thought that (as in the past) static charge was causing this and upon further inspection find that the powder flakes are stuck tight to the plastic! I dumped all the powder out and pulled the tank off the throwing section and tried to wash it out, not even close to removing it. It's as though it's welded to the plastic by chemical leeching, reaction??? Has anyone had this happen? I'm wondering if it's the batch of Titegroup or the newer powder and the older (circa 1975) plastic in the powderthrow. Link to comment Share on other sites More sharing options...
bofe954 Posted May 26, 2011 Share Posted May 26, 2011 (edited) Friend of mine showed me that recently with titegroup and a Hornady powder thrower, I don't think his thrower is from the 70's either. I have some titegroup that's been in my Dillon thrower for months and it isn't doing that. Don't know if it's the plastic composition or if titegroup changed I guess...But you are not alone.

cdrissel Posted May 26, 2011 Share Posted May 26, 2011 Could be static, do you live in a dry environment? Try wiping it out with a dryer sheet, after you get all the powder out. Link to comment Share on other sites More sharing options...
azrik Posted May 26, 2011 Author Share Posted May 26, 2011 (edited) It looks like static may had initially stuck the flakes to the hopper but they were on there tight. After scraping them off with my fingernail they left a frosted / sandblasted look to the plastic. This reaction reminds me of when a rubber worm melts into a tacklebox tray.

Too_Slow Posted May 27, 2011 Share Posted May 27, 2011 It seems to be the plastic that RCBS uses. The same thing happened with my Chargemaster 1500 both the clear section and the lower opaque section. Brian Link to comment Share on other sites More sharing options...
azrik Posted June 4, 2011 Author Share Posted June 4, 2011 Talked to RCBS via e-mail today. They reminded me not to store powder in the hopper, quoted the instruction that said so. "Powder should not be left in the measure, as it will deteriorate and may clog and jam the measuring cylinder and etch the powder hopper" ...and told me a new hopper was enroute no charge.

kalaur Posted June 5, 2011 Share Posted June 5, 2011 This happens to me when I leave my powder measure in sunlight with powder in it. I shoot quite a bit of titegroup, and generally always leave powder in the hopper, and the only time its actually 'stuck' in the hopper is when I didn't cover my press for a few days and it sat in direct sunlight. So either empty the hopper, or if you're lazy just be sure to cover up your press/hopper when you're done loading for the day. Link to comment Share on other sites More sharing options...
