Thanks Tinman. This has been very helpful.
I also spent some more time viewing the Hornady videos again. Hopefully, I can get the kinks out soon.
As you suggest, some of the issues may be a result of the current bench mount and my lack of experience with getting consistent progressive ram pulls. I've ordered the optional steel mount but it has not been received yet.
I'll check the bushings for any chewed up edges.
One of the things that the Hornady video alludes to is the mis-alignment of the primer shuttle guide rod (e.g., the bent rod). I assume this is done from the allen head screw on top of the press. I'll check this per the video.
