My supply of AA2520 is dwindling, and I'm looking for a replacement since no one seems to have any in stock. I currently use it in 6.5JDJ, 309JDJ, 358JDJ, 375JDJ, 223 Rem, and 308 Win. I'm looking for one powder to use in all of these that will meter well through a RCBS Uniflow powder measure, and of course is in stock somewhere. Thanks in advance for your suggestions.
