Never done it, but seem fairly easy, IF YOU CAN FOLLOW DIRECTIONS!. Don't want to sound like an a$$, but their are some things that have to be done just so or else.

Think about getting a NEF handi-rifle. Can be had very reasonable, comes in a 223 bull barrel and I had heard they were coming out with a 22-250as well. Can put an inexpensive, quality scope on it and be in at or about $200-$250.
