barrel nut does not fit.

[Fuj']

I tried both ways to see IF the nut would slide down the barrel to the threads. Neither would. one nut goes in like the pic above Other nut engages threads and stops immediately. Both are small shank nuts.

I have looked at the threads on barrel and nuts and cannot see anything visually

I tried fully seating the barrel in the action and when it stops I can look in action and still see threads visible so beginning to sound like something with threads on barrel. action was blueprinted

I'm reading this and just shaking my head. It's obvious that you do not have an understanding
of changing out barrels on Savage rifles. It worries me more that if you do figure it out, now you
have head spacing to deal with. Not to be rude here but, take it to a gunsmith and all your body
parts will thank you later.
