I have been working with Ruger MK. III target pistol, Ruger 10/22 in Hogue stock with Nikon (Philippines) 4X, and circa 1950s Marlin 39. I am trying to improve my ability to hit within a one-inch circle squirrel or rabbit's head. Much of my work to achieve the goal has been by futzing (technical term for spending a great deal of money before analyzing specifics of how to achieve intended goal) with firearms.
I am now at the stage where I request information from experienced 22 LR shooters. Having large quantities of standard Hi-speed 40-grain solids and 37??- grain hollow points to use, the range at which my one-inch circle ceases to be routine is about 35 yards. Since I have never owned a target rifle or shot any target ammunition, I'm beginning to think 35 yards is it unless I invest in different firearms and hugely more expensive ammunition.
