The only way to know is to shoot both.
In this model of Winchester rifle,there is no difference in value between the round or octagon barrel.
Who made it, what caliber is it, is it a rifle, shotgun or hadgun, how long is the barrel, is the barrel round or octagon, what is the stock made out of, what is the serial number(if any)? Who made it, what caliber is it, is it a rifle, shotgun or hadgun, how long is the barrel, is the barrel round or octagon, what is the stock made out of, what is the serial number(if any)?
None of them say. 22 short, long, or long rifle round barrel 12-A octagon barrel 12-C 22 short (octagon) 12-B 22 Remington Special (octagon) 12-CS
About $400-$450, dependng on condition. Octagonal barrel indicates made before WW II, changed to round barrel after the war.
I can give you a more accurate value if you will provide the serial number(to determine the year of manufacture). I will also need to know if your rifle has any special features such as a takedown model,A button magazine(half magazine),special wood,pistol grip buttstock,round barrel or half round half octagon,or full octagon barrel etc.
You have not yet asked us a question. Want to back up, and take another run at that?
Need to know type of action, all specifications such as barrel length, round or octagon, and any markings on the gun. sales@countrygunsmith.net
