I just received a drop-on barrel that I custom ordered for my Savage 110, obviously my first time doing this. I took off the old barrel, and when I put the barrel nut on the new barrel, it seemed to go on somewhat hard. It went on by hand, but just a little hard. When I went to add the recoil lug, it wouldn't go on. I tried gently threading on the action...no go.


I measured the thread diameter of the new barrel, and it was 1.064 or so. I measured the old barrel...1.055 or so.


At this point, I was thinking that I ordered the large shank rather than the small shank. Nope, my order stated small shank.


At this point, I was thinking that they mistakenly made the large shank for me. Nope...this is the confusing part. The vendor's website states 1 1/16" for small shank, and 1 1/8" for large shank. I have not contacted the vendor to ask them, so I would rather leave their name out until they have a chance to make things right.

To add to the confusion, I'm getting mixed information when I search online:
THIS LINK suggests that there are 2 sizes: 1.055" and 1.120".
THESE barrels on Midway say small shank is 1.062" nominal diameter (1 1/16")

Now, I'm really confused. Can somebody help me, please?
