The one group with Federal HV Match was 5.0" an the second measurement was an obvious error at 0.75".
To call either Federal HV or the standard velocity "Match" is simply false advertising!
Shot off the last of my Eley TENEX last week at 100 yards. The first five measured 0.91 and were high; using the "9" as my second aiming point the five shots measured 0.45.
Shot with the Cooper Montana Varminter off a bipod. The last group of five with CenterX measured 0.90"
Some rifles just shoot everything well, centerfire or rimfire. Others have preferences that may only exist with certain lots of ammo or very specific handloads.
If you happen to have such a jewel, keep it for as long as it remains a jewel. I have a half dozen or so such rifles, they will go to my heirs.
I hear stories about such rifles, quite often. If they're off the shelf, factory rifles that is a blessing, like winning the lottery.
A long time back, one of the local gunsmiths/gunshop owners, did me a real favor. Les Viel was his name.
He had just received a shipment of new in box, Remington 700 rifles, all chambered in 308Win. All had iron sights back in those days. He allowed me to take a half dozen of those rifles home, clean them up and take them to the range, with a half dozen different types and weights of ammo. None of them shot well IMHO and I cleaned them up, took them back and declined to purchase any on that basis.
He had another half dozen and allowed me to try them in the same manner, with the caveat that "if you mark any of them up, you buy them."
The second batch was fired with the same batches of a half dozen different brands/weights. One of the six didn't care which type or weight was loaded, it just shot them very well, better than any off the shelf sporter I had used to that point. Another shot some of the ammo well and the rest were mediocre at best but acceptable for most hunting conditions.
I purchased the Remington that shot everything well. I still have that rifle and it has over 5000 rounds down the tube. It's not as accurate as it was new, but it will still shoot everything it's fed well. I often use that rifle for teaching people how to shoot.
I recently purchased a Tikka T1, it loves Aguila. Especially the lubed lead offerings with the "Eley Prime" label in the upper left corner. Under absolute calm conditions, off the bench, on stable fore end rest and rear bag, it will shoot honest 1/2 moa. I shot a grouse with it at 100 yds last Tuesday. This was under field conditions, off a monopod.
Yeah, I know, not a big deal for some here, especially Paul T, whom I saw shoot a small marmot at just over 100 yds with that lovely Tikka T1 he built up. That shot impressed me enough to go out and purchase a new one. To tell the honest truth, I wouldn't have even considered taking a 100 yard shot at a grouse before I had this rifle.
My goto rifle before this, was a lovely Brno #2 because I felt I couldn't find another 22rf that was so dependably accurate, even if it is choosy. Luckily it liked the Aguila ammo I have so much of on hand.
Ganderite, Jim, I had one of those 10/22 clones and couldn't get it to shoot anything nearly as well as what your pics show. I've had off the shelf Ruger 10/22 rifles, with wood/plastic stocks that I couldn't get to shoot well either. Maybe I just didn't like the aluminum receivers??
I've had the Norinco Brno clones and they were OK but nothing special.
I haven't shot competition, other than friendly matches in years. Work, time, interest kept getting in the way. That hasn't diminished my interest or enthusiasm for shooting, hunting, building what I want to try out one bit. Much like yourself but without as much energy.
