You're welcome but you raise some issues and questions. I'm not sure the metallurgy of the Krag barrel, 120 years old, can or will stand up to a cryo treatment like JP does on their contemporary barrels. You're comparing apples to oranges, possibly. Never heard of that done.

Another issue is whether Perry allows altered barrels to qualify. Paul would know that.

A third, and probably the biggest issue to me, is that these Krag rifles, especially the ones with good bores and tighter chambers, are VERY capable of shooting MOA, even at longer distances! I have been doing this recently and have been getting more consistently able to do so regularly, with my hand loads. Others on this forum have done the same. It's not a deficiency of the barrel metallurgy that prevents many of us from shooting our Krags well- it's a deficiency of our shooting skills and ammunition. Again, this is with a good Krag. There are many out there.

I say the above if I'm hearing you correctly that you want an "advantage" to get you shooting well enough to go to Camp Perry.

I'd like to hear other Krag-philes chime in on this.

But, interesting idea. Goods luck and keep us informed.
