Doesn't really work for the calibers you list.
But W748 is a great powder to have plenty on hand as it can happily cover a huge range of calibers.
I use it in
222
30-30
307 / 308
45-70
Always nice to have something that covers multiple applications and because W748 isn't new and trendy its been generally pretty available in the last few years while plenty of others have been unobtainium.
