I was told this would not reliably feed challenger ammunition, first 3 boxes I had to feed it, were 2-3/4” challenger target loads lol 2 boxes of 1 oz slugs and 1 box of 7.5/1-1/8oz target load(the absolute minimum as per the operators manual), I can tell you that, directly out of the box, i removed the barrel, bolt carrier and gave both and the receiver a good cleaning to remove any factory shavings and shipping oils. Re-lubricated with Lucas extreme gun oil, and immediately fed it what i was told it wouldn't like, and it ate it like candy.
It is not made in Italy, so the finish is not as thick, the burrs are not as meticulously shaved off, and the name is not as established, but the Clone works every time i pull the trigger.
As an Italian, I approve this bargain. (Only lost the star for the slightly chipped Cerakote out of the box, but again, not made by neurotic Italians lol)
