I don't know about you guys but I'd actually prefer slower animations really, I mean everything between discarding the empty magazine and bringing the left hand into view again (like opening the magpouch, taking out the new mag or clip, that kind of stuff, it takes longer than you think) just seems to be cut out or played in fast forward.

Though I agree some parts of the animations may be snappier.

...lol I only now, after spending some time thinking this comment out, writing it down, thinking and editing the rough draft (yup, this is that important to me ), realise the OP's about bolting rifles between shots.
My comment, though now slightly off-topic, still stands. In regard to the OP I think it's pretty much fine as it is now.
