Why are you shooting so far out, especially if you're new to shooting? Defensive situations usually happen at 7 yards or less. Bring that target in to 5-7 yards and work on your trigger control and grouping at closer distances. Until you learn the basics and learn your gun more, there's no need to put the target out far. There's no shame in having the target close. It's better than having out a mile and not hitting anything.
