It occurs that it might be of interest to share a couple of pics that fairly represent the devil that drives me on the quest for consistent precision with this project.
What is my rifle capable of? I mentioned in comments to Jimy in the process of testing loads that I shoot standard RF ammo before and after. It serves as a reminder of what I am chasing. So if the average is in the 2's for Wolf and 3's for Norma TAC, what is the best they have done at 20 yards?
Meet my own personal devil:
Norma Tac; 5 rounds @ 20 yards, and please note this particular groups was #2, or the last round after shooting the CF rounds that day.:
Likewise, the best of the Wolf was also the last round after a CF test. Wolf in a harsh mistress.
