I went to load some Lee 457-405-F bullets (approx. 390 gr from homemade Lyman #2) for my 450 Marlin (1895M), but ran into a problem (potentially). I have never loaded this bullet before and bought some Alliant Rx7 to start with. Never have used Rx7 before, I doublechecked and reread the description of it in my Lyman 48th. It says Rx7 should have "a mix of red, yellow, and blue identifying granulations" (p67), but upon opening my bottle, I see no such granules. All I see are goldish tubular shaped granules. What gives? Has Alliant changed this since the 48th edition was published? A quick look at the Alliant website didn't help either -- they don't mention the colored granules.
Secondarily, has anyone have any experience with this combination?
Thanks,
Josh
