Speaking from experience, I have been to several 22LR competitions and 300yds is the maximum yardage I’ve seen to date, using match grade ammo such as Lapuas Super Long Range or Norma Long Range, Eley Tenex or privately loaded rounds. 

Typical over-the-counter standard ammo such as the CCI or Federal would be pushing it over 100yds. Of course, you will have your guys who claim they can hit a Quarter at 500 yds with their 1964 Stevens bolt action but it’s not reality in most cases. 

Hitting a pizza box at 300 yds. is not what would be considered accurate shooting. I’m talking about shooting a 3 shot group in at least a 4″ circle whereas competitors want to be shooting much smaller groups. 

So, my opinion and answer are unless you have a precision rifle and hopped-up ammo 100 yds is about it and up to 300 if you have the equipment. Just my opinion.
