I don't have a problem with many of your posts. I don't really have a problem with your fetish for lever guns in a SD role because in many situations I think they'd work quite well.You may thus want to consider a long gun that can go from completely unloaded (and thus legal everywhere) to being able to fire a few shots in as little time as possible. Some good candidates are double barrel shotguns, pump shotguns, and lever guns. All of these can easily have a few shots loaded in short order - much more so than a gun with a detacheable magazine. Plus, they are not "evil scary black assault weapons" - they are generally seen as hunting guns - and that can very much matter, depending where you are.
What I do have a problem with is when you go off the deep end and type something like you did above (in bold). Espousing the notion that a lever gun is faster to load than a magazine fed rifle/carbine is arse hattery of the highest order. The idea is completely and totally backwards. The truth is that by the time you get your third round into the gun I will have inserted a 30 round mag, slammed the bolt home and be ready to rock.
