Dies are some of the cheapest products on your reload bench...nowadays they are the cost of a pound of powder, or a box of 20 bullets in most common calibers...
for most calibers I load for, I have both Lee and RCBS dies for the round...
If nothing else, if I am waiting for a part for one set to come in the mail, I'm not down until it gets here..
I just use the other die.. I prefer Lee Seating dies over RCBS...
My usual way of reloading a case, is to first deprime it with a Lee Universal depriming die..., the size the neck with a Lee Collet die...
then use either a Redding Body die, to bump back the shoulder if needed.. or either an RCBS or Lee F/L die, with the expander ball out, from a caliber size up die ( for example : use a 260 die to be a body die for the 243, to bump the shoulder back) then it gets annealed... and then primed...
Then load the rounds one at a time...
I've loaded bullets enough in several dies over the years, the dies have worn to where I don't even have to use the spindle in the die.. Like my Lee 223 dies....243 also...
