I have a 310 set in 222, and I have seen the reference sheet on Castpics, but I cannot find an answer to my question. Namely, can my 222 set also do 222 mag? I see some that list the 243 and 244 on the same dies, so I thought it might work. I cannot find a reference for the 222 mag in a 310 tool though, so I am unsure. Would just like to know for future reference. Thanks, Billy
