I too cast and load all year. I just want to use this time of year when it is tough to get to the range to get ahead on my casting and loading. I tend to load handgun in bulk, but not rifle.I like to keep more rifle brass unloaded as I am much more likely to want to load it for a specific application.
I do have 400 plus 405 plain base cast for the 45-70. I will probably end up casting that many more as the year goes by.
