rcbs uniflow damaged by powder

[LiveLife]

Quoheleth, I have two Pro Auto Disks (one dedicated for W231/HP38 and another for other powders) and I have rarely poured back the powder in the hopper the past 15+ years. I just leave the powder in the hopper and add more when I reload (Yeah, call me lazy).

No reaction between W231/HP38 powder and the plastic of the hopper. I have also left HS6, WSF, Bullseye, Clays, Promo, Green Dot in the hopper on several occasions over the years without any noticeable reaction too.

My auto disk had a reaction with 2400 once, messed the powder up and stained my measure bad.

There is one other option: Replace the hopper with these Sinclair products.

Had the same thing happen in my Uniflow with Bullseye. Never happened in my Lee Perfect Powder Measure. Hmmmmmm............

rcbs contacted me today and they are replacing the cylinder no charge. customer service is alive and well at RCBS.

This is interesting. I asked a parallel question last fall about leaving powder in my Lee powder measure --- should I toss the powder. Consensus was "don't sweat it" and "not a problem." http://www.thehighroad.org/showthread.php?t=487000

Wonder if Lee uses different plastic than RCBS, et. al.?

The answer is: There's a huge gap between the preferred practice and what's allowable or physically possible. Ie, you CAN build a campfire on top of your stove to cook on, but most people usually simply rotate 1 of the 4 knobs.
