Not a silly question. No problem shooting 2 3/4" in a 3" chamber. This is probably a carry over from blackpowder days. Although, I don't believe there were 3" chambers back then but old tales do hang on. Youd do need to clean the gun occasionally, though. Also, Chris question was wise to ask. I'm borderline obsessive when it comes to firearms safety. BTW, I've never heard of the Yildiz brand. Presume it is Checzlosovakian import or some such.
