I own a 510. I learned to shoot with it, as did my mothers entire side of the family (all deceased now, born 1916). My sisters and I learned to shoot with the rifle, (1960-70's) and my kids have (or are doing) the same. Probably my grandkids will continue the tradition. In our family it is simply "the .22". the gun has fired...I'll guess...50K rounds, all single shot. It was the main pest gun on the farm for decades, if we notched the stock for every vermin it has killed it would be a pile of wood shavings.
It teaches a shooter to use aimed shots, and you'll never forget to turn off a safety when shooting at game. The long barrel is quiet, and it's a heavy, steady gun with a heavy but crisp trigger. It is unfailingly reliable.
I have a number of .22's to my name (win 61, 62A, 90, SW MP15-22) but if i want to hit something for sure, the 510 is the gun I use.
