It's a pain. Like building a ship IN the bottle.. I use and extension and do it by hand.. All we're doing is squaring the shoulder.. still it is truly a pain and the lathe ould feel soooo much better.. Also I forgot my normal caveat.. The K-Hornet is not a way to add performance, it's a way to add lifespan to your brass.. Good luck! Just a note. Sold my last K-Hornet, down to just 3 hornets, a Kimber, a M54 winchester and a CZ527FS.. The winchester is original(cost too much to change it), the Kimber too. The CZ shoots too good to change.. Ain't life hard!! Really the FS CZ will easily shoot better than the Kimber and with facotry ammo. It really likes handloadsm especially with the 35 grain VMax bullets.. If I could stand to sit long enough I'd try calling up a Bob before the local season ends.. I may tru anyway!!
