Ease of manufacture
In this model of Winchester rifle,there is no difference in value between the round or octagon barrel.
Weight is the main factor
Handgun projectiles are fired through shorter barrels which lead to a reduced production of muzzle energy.
Manufactured from 1929-67. Pre WWII production will have octagonal barrel, pistol grip stock and slide handle will be checkered. Post-war models will have round barrel, plain stock, and grooved slide handle. The capacity of the rifle is easy. Fill the magazine tube and add one (for the chamber) and you have the rifle capacity. It should be about 14.
If barrel is round, it is a post-WWII Model 29. If the barrel is octagonal, and the grip is checkered, it is probably a pre-WWII Model 29. If the barrel is octagonal and the stock is plain, it is likely a Model 25. That's as close as I can get sight unseen.

The ruger rifle
Neither. The shape of the hut is never mentioned in the books, but is octagonal in the films.
For this type of coin a denomination an the shape Octagonal or round will really help.
All of them are.
