Hello again. I was able to slug the barrel with a .224 35grn bullet which seems to show that the bore is ~.222". When I insert a live 22 hornet cartridge into the chamber it doesnt seat fully, but it doesnt seem to be the rim. Its feels like its catching on the cartridge shoulder or (if the bore slug is correct) that the bullet is slightly too large to sit in the throat of the bore.
Edit: yep, pulled the bullet out of the case and the case sits perfectly
