I think I'll actually go with guns I have fired, unlike most of you.
Remington bolt action .270 which has the flatest trajectory of any caliber. Reach out and touch someone.
My pistol, a Smith and Wesson .357 revolver with a 6 inch barrel. Extremely well balanced which helps with accuracy. I am deadly with it.
7.62 Russian, made in 1941. Sniper rifle. I sold my 30-06 when I fired this gun. Open military sights. Again, when I pull the trigger, something's gonna die.
Remington model 1100 semi-automatic full choke 12 gauge shotgun loaded with 3" nitro mags.
