Hoping someone can tell me what I have here.

Can someone decipher what I have here and tell me if it is good/fair/bad. I have no idea what the tophat is set at as I have no tools to determine this. Power wheel is set at 10. Any input would be appreciated if there is something I need to try different or leave it where it’s at and just get after it. The shots are still a bit louder than I would prefer, but have done about all I know how to do.

Here’s what I have:
Stock Talon SS .22 cal
12″ barrel
Shroud baffels made from hair curlers, brillo pads and washers
Front bushing drilled
Frame drilled under handgrip
tank filled to 2900 psi
Beeman Kodiak extra heavy pellet (no gr. wt. on can)

1. 760.8……….11. 771.6……….21. 748.3……….31. 751.1
2. 766.5……….12. 769.4……….22. 759.0……….32. 750.7
3. 784.5……….13. 760.6……….23. 752.6……….33. 748.2
4. 777.5……….14. 753.4……….24. 755.9……….34. 744.7
5. 783.2……….15. 751.0……….25. err-2………..35. 738.2
6. 775.8……….16. 750.4……….26. 754.8……….36. 737.3
7. 774.9……….17. 757.7……….27. 755.6……….37. 736.5
8. 770.2……….18. 769.8……….28. 755.0……….38. 735.3
9. 777.2……….19. 766.4……….29. 753.4……….39. 734.9
10.771.2………20. err-2 ……….30. 745.6……….40. 734.1

Here is the target I shot getting this string. Before I catch hell over the grouping, this was basically shot off-hand, all 40 shots across the chrony just leaning across the bed rail of my pickup, target at 30 yds.
