This may be a bit of an equipment specific question but I'm thinking someone may have experienced the same thing.. I have the "standard" (not the pro model) powder measure on my turret... As such there is no "turn off mechanism" for powder so if you take off the hopper, in essence powder is falling out all over.. With that said, I finished reloading about 175 rounds today but the hopper was half full.. I wanted to dump out the hopper but to accomplish this, you basically have to unscrew the measure from the die, and flip it over as one piece with the disk still in place.. Just wondering....this would require taking off and on the hopper regularly for everything from disk changes to emptying the hopper.. Is it ok to keep screwing this thing off and on? *** EDIT ok never mind I found the swivel adaptor for it... There are so many ancillary parts you find for these things... Would be so much easier if they just sold it all together.
