I appreciate the replies guys, I have tried hand cycling both full clips and never once had a single round hang up. And I have inspected the fronts of the bullets and I can't see anything that would show any kind of deformation or catching when loading. Also, I have done this several times and I am still a little puzzled. I will try and put a few more boxes through it and see if it settles a little.

Thanks for the recommendations gentlemen.
