I take a semi auto rifle any day over an leaver action.
This is true. When you shoot at something, there are some basic mechanical things that must go on in order to hit the target. Of those things, two of the most important are sight alignment and target aquisition (called sight picture, but we'll use the previous term so as not to confuse anybody). Every time you move a weapon you must first get these two things correct before shooting at the target again. Target aquisition is putting the top of the front sight post on the intended target area and keeping it there whilst you draw back on the trigger. Sight alignment is getting the correct sight picture where the front and rear sights are in the proper aligment. Without correct sight aligment, you may have the front sight post on the target, but your bullet will shoot to the side (or up, or down).
Computer games have gotten pretty good at duplicating what target aquisisiton feels like in real life with a computer modeled weapon. What they don't do is model sight alignment. You don't have any controls that allow you (or force you) to have to align the front and rear sights in the verticle and the horizontal. Just press RMB and the game automatically does this for you. This is where some of the modeling differences start to deviate from real life to the point where you would do things differently in the game.
Take for instance the above comment. This is completely true IRL. The advantages of a semi auto rifle are not just in the increased rate of fire, but in the weapon's stability while shooting. When firing a semi auto, the rifle moves a negligable amount (from recoil) and quickly settles back to the shooter's natural point of aim. This means that the sight aligment will stay very close and the target aquisition not much worse. You can easily shoot properly aimed individual shots with a semi auto almost as fast as you can squeeze the trigger. With a lever-aciton, the process of racking the lever disturbs not only your target picture, but also sight aligment. For every shot on a lever-action, you must align the sights and aquire the target with a proper sight picture each shot. This takes a lot more time, in my experience than with a semi-auto. Clear advantage to the semi-auto.
But in a game, things are different. Even the game mechanics may be skewed. Josh, for some reason allowed us to fire a Winchester 1873 much faster than an AR-15. Fine. Whatever. That's the game we got, unless you get PC mods, so in the game, the lever-actions work much better than the semi-autos. So much so that halfway through an Idiot/Savant Cowgirl playthrough, I took out all the Deathclaws at the Gypsum Train Yard with a damn BB gun. (Seriously, I'm not kidding. +70 crit damage on a BB gun FTW.)
