prevent powder damage to uniflow hopper?

Is there a trick to keep bullseye from burning into the acrylic(?) hopper on a uniflow powder measure that everyone but me knows about? 

I know you aren't supposed to leave it sit in there for extended periods but man oh man it gets sticky to the sides in a day or so.

I don't  use BE in my Uniflow, mostly in a vintage Bonanza fixed rotor measure and a Lyman 55.  I just wipe them out to get the BE loose and dump it back in the bottle.  Some recommend wiping the inside of the measure with a dryer sheet to reduce static cling but it hasn't seemed to help, at least for me.

Mine works - no discoloration or static cling.
Hope this helps.

I have four of the hoppers from Ward @ dramworx and can report N310, N320 and longshot do not stick/cling to or discolor the pyrex.

I'm not sure what you are asking.

To keep the plastic from turning yellow-brown empty the hopper between loading sessions.

If you are getting powder sticking to the sides by static electricity then a humidifier will help and I've heard of people wiping the hopper with anti-static dryer sheets. I've never seen the need.

If you are getting the powder to stick to the sides by some chemical-mechanical means then I have no idea. I've never seen a power get sticky or gluey.

Bullseye destroyed the hoppers on both my Lyman 55 and RCBS Uniflow powder measures. The powder ate right through and pitted the hoppers really bad. I had to replace the hoppers. On the other hand, I have let Bullseye sit for months in a Dillon powder measure and there were no ill effects at all except the hopper turned a little darker shade inside.

My hopper on my Uniflo turned black with deep scars etched into the sides.  I called RCBS and they sent me a new hopper, free of charge.

I always empty the hopper on my RCBS Uniflow after throwing and bullet placement.  Never any problems with Titegroup, BE-86 or CFE.

Somewhere on the internet I ran across several suggestions for taking a plastic pocket meant for 3-ring notebooks and cutting the plastic, rolling it into a tube and using it as the powder hopper liner. I did this on my Dillon SDB and Hornady LNL, but will add that I pour out the powder to a working powder canister after loading. I use powder baffles and the plastic liner stays in place.

I grounded both of my presses to drain static charges and it seems to work. My day job is big on grounding everything to prevent excitement.
