Dumb reloading mistake - need a solution

I was loading cowboy .38 spl. ammo on my Lee Turret press and I recently switched it over to my Dillon 550. In setting up the dies, I apparently flared too much and crimped too little - the foolish part was just eyeballing the rounds, instead of testing them. Now I have 300 rounds of ammo that won't feed.



What's my solution?



Go buy a Lee Factory Crimp Die?



Run them back through the original seating die, readjusted?
