Since it shot thar good, just run a dry patch through the bore before you shoot your ammo, for zero. Then don't clean it again until the groups open up. ha
Wow! I take it you mean the case was stuck in the chamber? Or was the bullet stuck as well (as in a squib load where the powder doesn't ignite). Just curious.
It was not "finished reamed", i.e., short chambered. It was a "Friday Afternoon" Rifle! ha We all have either seen or heard of one, pretty common nowadays, unfortunately.
