There are reasons why “scout rifles” are in .308, rather that trying to improve on a perfect caliber you should learn to accept the reasoning behind the choice of that round and the scout concept, having used a .308 in combat and knowing the ballistics of the round by going to a smaller and lighter round you would not make any improvement nor would a military caliber be readily available, that is part of the concept and the weapon system, we are almost at the year 2020, if the box magazine has not shown you why it is better for all weapons then you have a problem learning, times are changing and going back is not the way to go!
I also love the 57 X 28, again do not fix something which is not broken, when they developed the round several barrel lengths were tried, the one on the stock gun was not the best, but it was in the “good enough” category, if you are concerned about .8 inches you have less problems than I do trying to conceal many more inches that you were issued by your Maker!
I do not care what you do with the others, throw them away for all I care, I do like Ruger’s and Colt’s but I tend to choose wisely when purchasing from either manufacturer, Colt has had it problems for many years and Ruger will make one gun which is almost the perfect gun and the next is not worth using for mixing paint.
People have every right to their opinions, but having an opinion and being right are far apart! The next article should be about if 9mm is better than the .45, how many times can that be argued?
