I like their universal decapping die. I have there sizing die in 9, 40 and 45 but in 9 the die doesn't size down enough to have enough tension on some brass. When case wall was less than 0.01" thick the bullet would fall all the way down in the case. When talking with Wayne he said that the external dimensions of the brass were correct after sizing and that it was working as expected. My RCBS die would work with brass that had the thinner walls without issue so I quit using the MA dies.
