I do like the buttstock shell holder, and I can position it so that it doesn't pose any problem shooting, but I agree about the rest. All good comments above. Thanks for sharing.
That said, On another note, though, after playing around with the bandolier a bit, I can see some very limited usefulness for it, at least in certain situations. It's nice to be able to grab a variety of ammo, that you can see visually, all with the same orientation. So in other words in a grab and go situation, a bandolier could be convenient. Otherwise a simple ammo can would probably be more useful for storage and range use.
"The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles." Col. Jeff Cooper, from The Art of the Rifle
