Deepcore--What ya shooting?. Im with ya all the way on the OCD thing for sure. Im not sure if i follow you on the pre-measure thing though. So you want to have powder pre measured and just dump it in as you load?. That seems a little strange. Let me know what you ae shooting and i will see if i have some brass i can just give you. Brass is not that costly at all. Send me a e-mail and see what i can do for ya.Your idea is sound,but your getting into a zone of not safe if you ask me. Powder measuring is the most important stage in reloading. Should be done with care as you load your cases.
I hope my post does not sound bad,Im sorry if it does. We are all just here to help each other. Send me a e-mail. I sell brass on the side so i might just be able to help ya out
