1) No problems, do it all the time
2) No problems, do it all the time. I load all my 68 round mags to 33 bbs for most games.
3) Especially any military grade, and I'd expect just any good quality real steel holo sight should be able to survive most abuse you'd give it in the field. Aimpoints are a bit tougher than Eotecs, which as I understand it was actually the deciding factor in the US mil adopting Aimpoints over Eotechs. That's not to say an Eotech wouldn't survice being dropped or bumped, I'm pretty sure it would, just to say that the Aimpoint is a bit tougher. All that said, you would probably want to take care of any holo that you bought. Cheap replica's almost certainly are more delicate, and if you're not considering a real one, you'll probably want to take good care of it.
