What this President did to those who were our allies in Afghanistan is morally indefensible and criminal. I have no doubt that good people in State and in Defense are embarrassed for the diminished status of America. Good for Catherine for making her feelings clear.
I've made similar observations with a number of cartridges. Approaching maximum charge they tighten up and then begin to spread out. You have a fine load that'll take anything you might encounter in NA and most of the world.
Clearly, your rifle wants to deliver for you. Eight shots into an inch is pretty good, especially with factory ammunition. The Rugers are not particularly attractive rifles, but they are workhorses. All of them that I have deliver the goods, and I do have a few.
