I started reloading 10mm ammo & the load I'm using is:
10.2 gr Blue Dot
180gr Hornady XTP JHP
Winchester LPP
But the question I want to know is how come on factory rounds the shoulder of the bullet seems to start a couple hundredths above the case mouth when seated, but when I do it seems to be pretty much level with the case mouth?
