While also being right on.
So I just finished loading a bunch of 308 with Hornady Nickel cases and 168 gr Match BTHP @ 2.8000 COAL, and I moved on to some Hornady brass cases and 165 gr SST w/cannelure @ 2.7280 COAL. As I was finishing up the first cartridge of the SST it looked and felt WAY too short. So I pulled out my calipers and measured them and they were exactly as they should be. The shape of the SST and the .072 difference in COAL makes the SST look really short. But when you put them side-by-side they aren't that far off.
It is amazing to me that we humans can sense a .072 difference in length.
