Those look good for a PR crimper. I find the GAEP easier to get pretty crimps with.
You might try trimming your hulls so that you don’t have as much excess plastic in your crimp to deal with. I think that will tighten it up nicely. You’ve got a good start on it!
I played with it for a little while on some 2 1/2" hulls I had laying around before trying it on an actual load, it seemed like with the precision crimper the further you rolled it the cleaner it got. Im assuming this is because it was heating up. I have a piece of pipe I slide the hull in to trim but I didn't trim those
I wanted a Gaep last year when I bought this one but ballistic products did not have any in stock, looks like they are still out of stock in the 410 now. I dont see them for sale anywhere else
