Lets start with the Not So Good. Hornady.....geez these don't want to work, not in .38/.357 anyway. Sometimes it feeds and sometimes it doesn't and sometimes it feeds the whole dang tube. Now Sierra bullets measure .356 or .355. They fall right through the die. Hornady bullets measure .3565 and they work better but they too will just fall through the die. So, they are next to worthless, at least in .38/.357 anyway. And yes, I replaced the innards thinking there was a problem...no joy. Now the good: they are cheap and come with the expander. Of course, if they don't work, then even if they were free they wouldn't be cheap.
Mr. Bullet Feeder (Minnie) The bad: it isn't cheap. Tax, shipping etc and it ran $140 and change. The good: it works! You get the die, the expander and a cute little Lee- type bullet magazine only MBF's is really well made. It digested everything I fed it and did pretty well on case as long as the bullet was hard-lubed and its diameter didn't exceed .357
I still have a set f Hornady dies in 40 S&W and .45 Auto that I haven't tried. I have a feeling though that they may being put on the block soon too.
BTW, if you ever wonder why the folks at MBF give you a spare set of bearings don't. Just be glad. I used mine 15 min after setting up the die.I pulled the wrong clovis pin.
