My liberty barrel will let a 123 SST drop out of the chamber seated to 2.233 but will hold one seated to 2.245.
I think my barrel will be fine and drop a factory 123 SST round after some more shooting.
Some of the group buy barrels are probably OK.
I polished the throat a lot and now all I see is a few small scratches on a 123 sst when seated to factory spec and they seem to be made by a little roughness in the throat on one side.
That is probably what is holding the round from dropping at factory length.
My barrel shoots good and I must have got lucky.
A little JB's or Iosso on a patched 6 mm brush and some elbow grease might make some of the barrels work out and others might not see a need to change their chamber.
