The kits work fairley well,there is however a problem with brass consistancey. Weigh some cases of differant brands and you will see what I mean.With that said,I have never used 22 cases for jackets,it's alot easier to buy prepared jackets and alot more accuracy will be realized at any speed due to the consistancey and quality of a commercial jacket
if you do get a kit ,enjoy!!!!! And welcome to the world of swaging
