Thanks for the responses. Looks like H4350 will be it.
I looked at a #3 in 22 Hornet the other day, I had not realized that they had such a heavy barrel contour. It balanced very nicely but the shop wanted $795 for it, so they kept it. Very neat rifle, I like the front sight band as well.
JB, I hope you'll do a 30-40 krag article featuring your #3 and load development!
