This is a bud's Feinwerkbau AW93
It has to be in the category of best, most accurate 22LR. Recently I was offered a used one, but the grips were not sized for my hand. I estimate that replacement grips were at least $500.00 so I passed. That Bud is having troubles selling his AW93, but some day, some where, someone with the correctly sized hand will love that AW93.
This Model 46 S&W has been a reliable and accurate 22 LR target pistol. I have been shooting this regularly in Bullseye Competition. I enjoy shooting a rare vintage (less than 500 made of this model) pistol. I remember where I was in 1968, and that was the year this was made. Brings back memories.
For the money, I have been very happy with the Ruger MKII
This is an accurate and reliable pistol, once I replaced the factory firing pin with a Volquartsen.
Factory firing pin peened itself to death. Soft metal.
I am going to state an opinion that others may not share. The best ammunition in a 22 LR pistol is the ammunition that most reliably functions the things. Having had many alibi strings, if the gun don't go bang, you drop points even with the most accurate 22lr in the world. These blow back pistols are sensitive to ammunition.
This shooter, a two times Bullseye National Champ, was using Lapua OSD in his Hammerli. Just shoot that well with one hand at 50 yards and 25 yards. The ten ring is four inches at both distances.
Same guy shot this composite group at a 25 yard reduced Bullseye Match. Just do this standing, holding your pistol with one hand, for ninety shots.
