Grew up with an "Ace" .22 my uncle gave me when I was 12yrs. old. I hunted with it on the sly until I was able to test and get a hunting license at age 15.

We found out we had to shoot ground hogs in the head or middle chest to kill them RIGHT there and the irons were all we had. We simply made 100yards, the limit and stocked and shot when they were out of range. Amazing what practice can do for your accuracy, even with the lousy sights on that little rifle.
