I have the right top punch, according to lyman.
I have several recommended top punches that still tend to ding up the bullets so a little trick I use is pinch off a small piece of paper towel fold it a few times,then wet it and push it up in the top punch.After a few bullets it will conform to any deviation and won't leave ring marks.Maybe a tad anal but I like clean looks as well.
Nothing wrong with a 2" group for hunting but yes you could probably tighten groups experimenting with different powders,alloy,fillers and seating depth..I agree with Gnoahhh as well, crimping isn't always necessary.
Good job overall for your first go round..
