Powder left in the dispenser

[tightgroup tiger]

Jeff H quoted asked.

Can we get a list of dispensers that are negatively affected by the powder?

I think a list of the most destructive powders would be more in order. I think the pistol powders that have the highest Nitro-glycerine content are probably the most destructive on plastic. (like tightgroup).

That's funny that red plastic Lee powder hoppers don't get like that. The hopper on my pro1000 is still resonably clean also.

Now that I think about it, with the rifle shells I loaded in the last 30 years, Ive used the same red plastic funnel and it is etched and stained to the point that powder doesn't want to slide through it anymore. I wouldn't expect the plastic back then to be as good as it is now so maybe my theory isn't valad.

I see no reason to leave the powder in the powder measure when one finishes a reloading session. It takes so little time to empty the measure and subsequently refill it that it has become part of myu SOP.

Bullseye discolored and etched my RCBS Uniflow hopper about 15 years ago after being left in the hopper for slightly over a month. Since that time I remove the powder after every reloading session.
