Savage .223 1:7 rifling problems

[Frankthetank1point0]

Update: called savage again the lady was again surprised by the rifling and helped narrow down the model of gun it came off from which is 12VLP sku#18464

Hello I bought a barrel off of ebay recently as it was a package deal with a stock I needed. Barrel is a factory savage SS 26" fluted small shank. Upon cleaning the barrel I realized it was a 1:7 twist much to my delight. Once I broke out my bore scope I realized the rifling was not normal because it has about a 2-2.5" long section at the beginning that is straight not twisting. I called savage before I posted the videos (see youtube links below) and the man could not give me an answer as to why it would be this way. Have any of you ran into this before?

That is fascinating...you may have the only factory gain twist Savage barrel in existence

I wonder if they will replace it for you...have you tried to shoot it?

I don't think it's a gain twist but maybe it is. I told the I spoke with at savage I'm not looking for a replacement or warranty as he seemed concerned with that and assured him I'm only looking for the how and why this barrel is the way that it is. I have not shot the barrel as I don't have an easy drop in action for it. Maybe I will borrow a 12fv 204 I sold to a buddy to swap the barrel and test it out.

I would vote mfg defect. Button rifled and the machine 'skipped' for a bit before it started rotating.

I just got some videos posted the rifling looks too uniform to be a defect. https://youtu.be/qRZpU49UquY https://youtu.be/v_zQ447N9qk

Strange indeed. Somehow the button for the rifling remained static for that first stretch. Curious to hear the shooting results.
