Whenever you pull the Bolter out (at least as the veteran) its cocks the weapon again. I’m not sure why this happens but personally, I can’t stand it. Cocking/charging the weapon increases the time between selecting it and using it by quite a noticeable amount.
The solution: Remove the animation altogether unless on a reload or first use.
I don’t understand what balance or mechanical need there is for cocking the weapon each time you take it out and on the “realism” (I use that term very lightly :P) each time you’re doing that you’re ejecting a usable round.
It’s been raised before. It’s meant for balance even if the animation used doesn’t really make sense. I think they should remove it and weapon switching should be instant but we’ll just have to see how the devs take the feedback on board!

FYI they changed that on bolter and autoguns a while back: instead of cocking everytime it does a couple other different animations when you draw
