That’s great! The reason I ask about the bore size is, I have a double barrel 10 gauge one side was .798 , the other .802 .... I think.
I took mine too a Gunsmith who specializes in old guns, he told me mine was safe too shoot.
But said due too it’s age, keep the shot load on the light side... 1 1/4 oz or less ..
Those # 5 patterned nicely...Congrats
