Help Troubleshooting Impact

All,

I cleaned my barrel and do not know if I bumped settings or if I damaged my barrel by using a brass brush.

My first plan of attack is to see if it’s tuned and regulator is working. I just ran it through chrony, can someone in the know please review and see if something stands out.

-max setting — 11 shots, 28 extreme spread, 925 average, 8 standard Deviation

-5 setting — 14 shots, 28 extreme spread, 888 average, 8 standard Deviation 

A setting - 5 shots, 20 extreme spread, 879 average, 7 standard deviation.



i went from averaging slightly under .5 inch groups to .75 inch groups at 50 yards. Thanks in advance 




 
When you were cleaning your barrel, did you remove the barrel with shroud to clean? And if so did you remove the barrel from the shroud and maybe the liner? I’d start checking the barrel cinch/lock screw or dial, maybe the treaded sleeve for the barrel liner, etc first just to eliminate simple things before checking your settings. If all is well then I’d start checking your regulator, hammer spring, etc settings. Hopefully it’s something simple.
