High end?? Besides the 54 Anschutz, we have in the used roster [when you can find them] [some can be found new]
Suhl 150 Standard, Remington 40X, Remington 37, Winchester 52 B,C,D,E, Walther KKM, Feinwerkbau, etc.
Then a definite step down, but still decent rifles: Anschutz 64, Sako Quad, Remington 541S & early T, CZ 452,453, 455, Certain BRNO rifles, Winchester 75, etc.
All the rest fall into "basic rifles" with varying capabilities. [You may not agree, but that's your prerogative]
You want the best....you spend the cash. A "high end" 22 rimfire with match ammo it likes should shoot into .25" or less at 50M for 10 shots. Dave.
