It is not uncommon for a rifle to have a minimum chamber and the FL die have maximum dimentions.
Under these conditions, the die might not be able to FL size the case enough.
I do wonder where the 260 cases originally fired in your friends rifle?
They should go back into the chamber, slick like owl poop.
So I guess the question is...
Are the fired cases from your friends rifle, or did you (he) get them from another rifle?
If so, have you tried cases fired from his rifle?
Is your FL die set all the way down, so you feel resistance when you pull the handle to the end of the stroke, and the ram "goes over center".
I had this same problem recently - a friend gave me 600 pieces of once fired .223 Lap brass, and they wouldn't chamber (expected, kinda).
So I tried a very good FL die - no good, so I tried a small base FL die - no good, so I tried a minimum dimension shoulder bump die - no good.
I finely had to take off 0.023" from a shell holder to get the cases to fit my chamber (snugly)... and my chamber accepts all factory brass, without binding... go figure ? :(
