Re-size a few of those 27.8 cases, to see how stiff they are going into the die.
Or measure just above the case web, and compare to some of your old Hdy loads, see whether there's a lot more expansion there.
I also wonder if Starline might be somewhat softer than Hornady. They don't all use the same brass alloy, each mfr has its specs, hardness, %compositions, etc.
I remember a while ago comparing Win brass to Remmy, and the Remmy was thicker and softer, the Win harder and thinner. Neither was a problem, just different. Rem brass primer pockets expanded faster for me than Win's, tho'. (Had the same thing happen in some 6.8 brass, SSA harder vs Rem softer. Both had their place to use however.)
