The best answer you can actually give yourself is by training with aforementioned firearm. Get out and shoot that thing and build your confidence. Im pretty sure after shooting a few hundred rounds you wont have the need to ask anyone what YOUR weapon will do. Get comfortable and multiple different ranges and know the dope for ur scope....
"It is the soldier, not the reporter who has given us the freedom of the press. It is the soldier, not the poet, who has given us the freedom of speech. It is the soldier, not the campus organizer, who gives us the freedom to demonstrate. It is the soldier who salutes the flag, who serves beneath the flag, and whose coffin is draped by the flag, who allows the protester to burn the flag." -unknown-
