It will all depend on the material the barrel is made of . Some "steels" will be fine at .020".Some will not .
There are many hundreds of guns shot every day with thin walls without indecent .As there are many cars driven in non roadworthy condition without accident or injury.
But one day the barrel might burst .Its a risk and its up to you to take that risk and the responsibility for it .
I could advise you based on long experience , having examined the gun ,I could advise you on charges and loads , but thats all it is advice .Its up to you to take that advice , but its up to you that if unsure not to use it ,which is always the safest option .
