I recently bought a box of Sierra Match King 155 gr Palma bullets just for a try in my Remington Long Range 30-06. My normal match style bullet in this gun is Sierra MK 168 grain and I get great accuracy at 200 yards, so I wanted to try this Palma 155.
When using my Hornady gauges to check the seating depth I noted the bullet's base is barely in the neck of the brass when the ogive touches the lands. I seated a dummy round 30 thousandths off the lands and the bullet doesn't seat in the neck very far at all. In fact, I can wiggle the bullet in the brass feel it move. Like I said, it is barely in the neck where the boat tail starts forming.
Interesting, it chambers just fine since the ogive is off the lands and the case and shoulder of the bullet is meeting headspace specs. Only thing is this bullet feels like a child's tooth that you can barely wiggle when they are nearing losing a baby tooth.
Since I am single loading this bullet from a bench, is this a concern? I suppose my Forster Ultra seating die is making the bullet seat concentric. I guess I could seat it a bit deeper to maybe 40 thousandths off the lands but my concern will be that accuracy is likely to suffer the further off the lands I go.
Anyone else had this question with the 155 grain Palma from Sierra??
