Whether it's Odin or Hornady, I'm sure it'll get resolved.
I just got off the phone with Tim at Hornady technical support. There are two barrel manufactures that have short chambers. But... this is not going to be a problem as the new rounds are going to be loaded at 2.200 right from Hornady. So this will give me a short .010 lead jump. As far as compressing the load this will only help accuracy as it eliminates any air pockets in the case. The rounds take very little powder to begin with, and Hornady said that the shorter chamber and the short lead jump combined with a more compressed case charge is only going to add to the accuracy of the rifle.
Although I could possibly see a problem with some powders that take a higher amount of grains and possibly some extruded powders that have a tendency to fill the case to a high percentage. They also stated that the shorter and compressed rounds still are within the Sammi pressure range.
