I was wondering if I would benefit from expanding 30-30, 7.7 arisaka, and 7.62x54R as a second step like pistol brass. These shoot boolits a lot fatter than the expander in the full length sizing die. I think I may have read that some cocentricity issues come from the expander pulling in a different direction when the brass is in the full length sizing die and doing a 2 step may be beneficial. I don't have a lot of brass in these calibers so it would not be much extra work.
