Think you'll be happy using them. I try to make it a habit to pull
a cast bullet after seating to mic. Also, flat base jacketed
bullets seat easier. Buying inserts is a cheaper/practical way
to get started, imho.
I use lyman m dies which are also 2 step expanders. Ended up
with seven of them. Wasn't cheap at 20 bucks each but I use
them a lot. It was a case of "cry once".
