Grendel working pressure is much lower than .308, .260 Rem, or .223, so I find that I never need to trim necks for length.
I also like as much neck tension as I can get, and since 6.5 Grendel is less than a caliber in neck length, I avoid unnecessary trimming if I can.
The only brass I've seen exceed 1.530" length is PPU, which is recalled.
I found with the Hornady comparator tool that I need to set back my shoulders .006" or I won't get bolt closure. I use the .350" bushing in the comparator set, and zero out on that once I install it on one side of the calipers.
