I support all the above, but its the shooter who is the expert not the rifle, the rifle just has to be capable of achieving what the expert requires and all new rifles do, be they Bleiker, Anschutz 54/30 or the Walther KK500.
Much of the group testing is also an irrelavence, but it gives most shooter the chance to see groups tighter than they do in their normal shooting.
.22lr is designed as as a cheap sporting ammunition, its manufacturing process is beset with errors waiting to happen, the case is too small to accurately size, the primer is crudely added, the powder is difficult to guarantee an accurate load again due to case size and mass production, the bullet is simple and crude cast lead, and is machin mass produced fitted for centrality and depth, its a wonder they do shoot as accurately as they do and is a credit to the care that the top manufacturers take to achieve the degree of precision that they do.
We also shoot 300 mt and use both factory and handloaded 6 mmBR, now that is accurate! But the case is sized to the 'nth, the primer is a precision part, the powder is individualy weighed (and we weigh to 0.02 gns), the bullet heads are precision parts, and again we check weigh them (they cost double a .22rf complete cartridge), the bullet heads are fitted in a micrometer set individual die press for depthe and centrality, and the lot is individually checked, and they do shoot incredible groups, but they cost £2.00 each! And its still a 60 shot match!
Several top world level shooters that we know haave said that group testing with less than 100 shot groups is a waste of time, one says 250. One, a five times Olympian told me all it proves is that the shots in the group were OK, it says nothing about the ones to come, he stopped other than basic testing a long time ago, but tells every one he does just to wind them up!
The KK500 is a superb rifle, my wife has one, but hers is in a Keppeler stock, nothing wrong with the standard stock, just she wanted it the same as her 300 mt rifle, she shoots RWS R50 ammo, and at bus pass plus age regularly shoots over 590, but then also did with her previous KK300.
If you want to shoot tighter, get a good coach!
Good Shooting, have fun and a merry Xmas
