Need help on this. I am looking at a C. Boswell in 500 Nitro-that has been refurbished. It is actually a 3 1/4 however I was told I could shoot the 3" as well..question is--will that diminish the velocity as it is actually bored for the 3 1/4. Also I have limited knowledge on this manufacturer other than the company made firearms from around 1890 to 1940 when supposedly the shop was destroyed in the war.. the owner is asking $21,500.. is that a fair price--
Please advise and thank you for your help.
