Yep! that's it! Any idea what 240gr bullet that is?

Although, I gave Hoot a few and he did have a little trouble with feeding. I believe it had to do with the angle they sit at in the mags. Mine have the front sitting a little higher than what Hoot had.

IIRC, the issue was more of the luck of the draw with how they were oriented rotation wise. With a 4 blade pattern, there are four 90 degree quadrants. While about 80 degrees or rotation in each quadrant positioned those blades without issue, there was about 10 degrees where they lined up with the barrel extension cuts so that they jammed up against them. That breaks down to I believe is a 1 in 8 chance of a bad alignment. Again, IIRC, there are other factors like how the cartridges ride while waiting to be stripped and cycled into the chamber. A little more tilt one way or the other could impact the probability of a bad alignment. This was not a paid proof of design study, just some loose experimenting one evening with dummy rounds. All contributing factors considered, there is a possibility for a jam. The odds of it happening are however, more subject to additional study. In real life, I suspect that the shooter has very little chance of controlling the contributing factors aside from loading the rounds one by one. Most, if not all dangerous game hunters do not use autoloaders for a reason. A 1 in 8 chance of losing a deer because your second shot jammed while regrettable, is far less worthy of concern than a 1 in 8 chance of getting mauled by a wounded lion.
