Geeze, Stan, how many 3" 410s do you need? These roll crimped once fired shells may not crimp so well when run through a star crimp die. Let us know how they crimp. By the way, the best .410 3" loader in the world is the Ponsness Warren Model 375. Price is $475 plus $38.50 for the 3" conversion. I bought a .410 PW 375 when I was in high school and it is still in the loading room. I turned 70 this year.
