That is where I am at. I have a 6" and 10" at the 20 yard range at home. I tell the wife and kids hit the 10" at 20 and you'll have no issues resolving intruders in the house. Then refine on the 6" to fix trigger control. But it seems I got a loooong way to getting near John.
I've been shooting since I was about 8 years old. Practice makes you better.
