I sometimes practice shooting left handed. When we're out burning ammo and what-not It's fun to mix it up a little, and make a little challange. I've noticed however that left handed shooting isn't too much harder for me. It does make quite a bit of difference with bigger guns, that kick more, but for .22's ans stuff you don't really notice.
One time I was like "I just can't seem to get light in the scope" It took me a minute to realize that I was leaning over the stock and looking out the cornor of my right eye.
And I thought my scope was broken.
