Hello all, Not a frequent poster but a lover of the forum and LC guns. I purchased a O Grade 12 Ga. Bushed strikers and two piece tang. The barrels have been cut to 29 inches however the screws appear unturned. Wood is in good condition with no cracks. During my first shooting I noted that fired hulls have to be literally pryed from the chamber. Unfired hulls drop in freely. I have cleaned the chamber and tried different brand shells. I have thought about running a chambering reamer but unsure if this would be prudent. Any ideas? Thanks in advance for your help. Mark
