All the above answers are "right"- when you measure with a dowell, against the closed bolt "in battery" and make a hash mark where the muzzle ends on the rod- you are right-if you add in depth of the headspaced ring that is inside the receiver. I always dis-assemble and measure from the exact rear of the thread lead to the muzzle- if you research Dave Riffle's book on "The Perfect Repeater" which the Model 12 most certainly is, you'll see the odd 26 & 3/4" developed barrel length when they had the ventilated rib for the 26" barrel guns on their Skeet guns..
