Spanky I am really not sure what went wrong, I will have to talk to the gunsmith who did the rechamber. He has been a smith for 35 years, has done thousands of chambers including full custom builds for bench rest shooters. He has done stuff in the past for me and I have always been thrilled with the quality. For some reason 25 grain bullets are key holing at 50 yards, and it appears that it is because of a poorly cut chamber. A spent case rotated in the chamber will not allow the gun to close, so there are definitely issues.
I really am liking the looks of the load data on the 17 Hornet, I may need to go that route.
