This. The Dillon trimmer does NOT chamfer or debur the case mouth. This does not present as much of a problem when loading boat-tail pills. But with flat-base bullets like the Hornady 2266, chamfering or flaring is almost a necessity. The Lyman M die might be one solution to your problem. This accomplishes the same task as an expander die for pistol calibers. Either that or chamfer the cases by hand or on a prep station as already suggested.
