There is a trick to get this thing to work. It will work for butler creek mags and ruger mags after you figure it out. I'll be honest, I actually bought this thinking that if it worked with other mags than surely it would work with the Eagle mags as well, I was wrong. It really takes practice to operate and after I damaged about 10 rounds of ammo or so, I think I've got it. If it feels like it's binding, don't turn it harder! It will dent or bend the brass case! I would not recommend this to anyone with intentions of using it for Eagle mags as it does not work too well.
Pros: works ok after you get the routine going
Cons: does not work well at all with eagle mags
