For all intensive purposes here in this blog the objective is not to go head to head and battle the universe but for you to stay below the radar and stay safe (That is subject to change in the future). While either of the above mentioned rifles will help you in staying safe they do require time in training and an ever increasing cost to operate I.E. ammunition, again they fill a niche, good for something but bad for others. In an ideal world we would have a special selector switch to go between small caliber short range to say an intermediate caliber to oh my god reach out and touch someone at a mile and a half. Well we don't have that capability right now so we stick with what we have, a rifle for this and a rifle for that but slogging around with two or more rifles is a little more than impractical.
Until science fiction catches up with reality or we grow more trigger fingers we will have to settle on using one rifle at a time and again nothing is perfect. Now another age old question you hear a lot is,
My second reason would be Ammunition, .22 ammo is dirt cheap as compared to every other caliber out there, it can be found in a hundred configurations from sub-sonic to hyper velocity and everything in between. While this caliber may not be a heavy hitter by any means it is not meant to be, it is primarily a plinking round or a hunting round for small game or birds and this will fit right in to a survival theme, it will keep you feed and provide a basic level of protection. Now will it take a deer? it does every season but it is the exception to the rule and illegal in most states. Will it put a 2 legged animal down? again it does every year but it wouldn't be my first choice. Remember in a survival situation you want to stay under the radar and out of trouble and maintain a minimal footprint, noise is something in this case you will be able to keep low.
In addition to being inexpensive it is also very light per round and that means that if need be you can carry huge amounts of ammunition, I am talking about thousands of rounds at a time, @ about 4lbs per 500 rounds you can carry a lot of ammo, what you lack in knock down you can sure make up for in capacity.You can break it down in one of two ways, larger caliber with less ammo or smaller caliber with more ammo.
and the sky is the limit. This is one of the big advantages of this type of rifle, while the .22 round may be small and underpowered for some things it is offset by ability to send huge numbers of rounds downrange in the blink of an eye.
Magazine's are being made that have a capacity of 20,30 and even 50 rounds, I think I even saw one somewhere with 100 round capacity. I would stick with the 30 rounders though as they seem to fairly trouble free and inexpensive.
