My rimfire collection:
Pistols: S&W Model 41, 6"bbl, Browning Buckmark, 6" bull barrel,
Long guns: Browning A-Bolt 22LR, Browning SA 22LR takedown, CZ-452 Varmint 22LR, CZ-452 Varmint 17HMR, Marlin 39A 22S,L,LR, Ruger 10/22 22LR w/ KIDD 20" 0.92 target barrel & KIDD trigger group, Remington 511 22S, L,LR.
Most accurate? CZ-452 Varmint 17HMR. Most accurate 22LR? Custom build Ruger 10/22 or CZ-452 varmint 22LR. The Remington 511 is a classic and is also seriously accurate with open sights -- but my eyes are too old to shoot it to its full potential. The little Browning SA is surprisingly accurate, also, shooting almost MOA at 50 yards.
Least accurate? Browning A-Bolt.
Most fun to shoot? Ruger 10/22 or Browning SA.
Best hunter? Browning SA.
Best 22LR ammo? Wolf Match Target, CCI Standard Velocity, CCI CB Longs
Worst Ammo: Remington Thunderbolt
Best bulk ammo? Federal AutoMatch at Walmart, if you can find it.
Best 22LR Target Scope? Burris FullField II 4.5-16X 42MM w/ Burris Signature Zee rings (although there are many fine scopes out there, depending on one's budget and tastes).
