I wanted to get some thoughts on comments I saw on another post. It intrigued me and I would like some insight.
the discussion revolves around a person setting their base to Ogive in a bolt gun and how hornady modified cases vary from fired and resized brass, due to changes from chamber to chamber. The final comment was the shoulder datum would be different resulting in a different bullet jump than anticipated.
If you push a should way back, say .02” and hold the BTO, would the bullet bury in the lands, or will the bolt hold the shell back? Would the bullet utilize the jump and be gone before the case expanded to fill the rest of the chamber?
I am a rookie, so I could be out in left field, but if you measure from base to Ogive, I felt that whatever falls in between those two points, should not matter.
What are your thoughts? Do people at the highest precision levels monitor the shoulder datum to Ogive?
