The older 10/22's were very accurate. I had one back in the 80's and it ran like a boss and could hit dimes at 50 yrds. My brother has a newer one, maybe 10 yrs old, and it's not very accurate. Like a 2 inch spread at 50 yrds.
With un-adjusted factory Irons, mine was some 8 or 9 inches high & left at 75'. That is unacceptable from any manufacturer.
