The farthest I have ever shot anything with a .22LR was prairie dogs out in the west. I was hitting them at around 130 yards pretty consistantly after I got the windage down. I have hit crows out to around 75 too 100 yards, didn't hit them every time at that range but several bit the dirt.
One thing that got me to thinking about this, is another forum I frequent where people target practice with22 rifles out to 500 yards. They put a 20 mil scope base on so they can keep the scope in mid range adjustment, and use basically high end tactical scopes for their optics, and also have tournament target shoots with the lowely .22 rifle. They use subsonic ammo so it doesn't lose it's stabilization when it goes subsonic.
At first I thought they were crazy, but it is starting to sound like a lot of fun. I guess before I got on that forum, I never knew that .22's could shoot accurately for 500 yards, and always assumed they were a 100 yard maximum rifle. I would never shoot at game at those extreme ranges, but at targets what to heck!
So this summer when I get my target range set up, I'm going to try this just to see how accurate my .22's are, and of course, the ammo is fairly cheap so it's not like it will cost a lot of money.
Have any of you guys ever shot a .22 at a 500 yard target? And What is the farthest shot youv'e ever made in any situation?
