The Powder Inc. loader comes with all the pieces you need to load the Dragoon or the Remington I have. Seems to be fully adjustable and even comes with different size Center pieces to fit the larger Colt arbor holes.
My only gripe is they use allen bolts for the adjustments so I stuck a strong magnet to the base to hold the allen wrench it requires. If they used slotted or phillips screws I could use my swiss army knife. Not a big deal, certainly not a deal breaker... I guess I could just change out the screws and be happy... nah, then what would I gripe about?
