TCMan I think we have the same book, the numbers are the same. I have tried the fast load with 322 and it was very accurate. I have been using the lightest load with RL 7 for my daughter it was best load in my gun but not by much several have can print one hole at 50 yards.
My daughter will not be using it this year as she will need more practice with a handgun. She will be using her .257 Roberts for another year.
I may take the little TCU out this season I have been shooting very well out to 200 yards with it, it shoots better than any of my rifles.
