50 yard zero will put your shots close enough at 25 yards you won't have to worry about readjusting. Depending on ammo you are only talking 4" difference at 100 yards. You won't have nay problems getting on target at 200 yards. Don't over think it, just get some good ammo and start shooting.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
