Is there anyway to get several small batches of powder? I currently load for the 270 WIn, 308 Win and 7mm Rem Mag. I have H380, H4831 and H4350. I would like to try several other powders such as H1000 and REtumbo and perhaps a few others. Is there anyway to get smaller batches of several powders as opposed to spend for a whole pound and eating the cost if you don't really get good results with a particular powder. Perhaps I should check at one of the ranges around Sacramento for other reloaders in the area. I'm just curious if there is not a sample pack offered by some company to try several powders. Sure wouldn't want to get a mixed up can of something!
