Geez, no contest, the 500 Jeffrey hands down any day of the week. Significant step up on the 470 Capstick in my opinion.
Feeding on the Jeffrey can be problematic, mine took a number of goes and the smiths did some wonderful things, but in the end it feeds very reliably....to the point that it's use on DG is done with great confidence.

The simplest solution is the inline magazine, usually 2 down and one up the spout. Mine is staggered and carries 4 down. They are harder to get to feed staggered but it can be done, just more work, which generally means more expense.
