I have a 308 Winchester bolt action rifle with a Shilen match barrel. I measure the length seated to lands using the Hornady OAL gauge. For most of the bullets I can feel a slight resistance / engagement pretty early in that the bullet clearly engages with something. Then if I apply just a little more pressure on the gauge, the bullet leaps forward quite a bit further.
The difference between what feels like the first engagement and when it is solidly jammed into the lands is as much as 0.150 inches, quite a lot.
Is this a common occurrence? Has anyone else seen this? Does anyone have any idea what might be causing it and if it is cause for any concerns? The rifle shoots well.
