It would take more than $3K in ammo... at todays prices $10K in ammo, for you to wear out that barrel... the cost of the barrel is tiny in comparison.
...Slow, deep breath in followed by two quick, shallow exhales, then one long breath out. It should sound like "HEE HEE HOOOOOOOOooooooo...HEE HEE HOOOOOOOOooooooo". Once your comfortable with that breathing pattern, try to sync the tempo up with your heart rate. "Lub-dub...HEE HEE HOOOOOOOOooooooo... etc". ~ CBruce
