The round on the right was seated to 2.265" and then chambered from a magazine. The round on the left was seated to 2.320", chambered by hand, released the bolt (check bolt for full battery), and removed with wood dowel. After it was removed it measured 2.309". The Sharpie acts like glue; they were both difficult to remove by comparison to no Sharpie.
With out the use of a dowel for removal; both projectiles would have both stayed in the bore, using just the bolt/charging handle to extract them.
