I find it slightly annoying when developers don't do their homework on how weapons function. For example: having to charge a rifle after reloading in the middle of the mag or pumping a shotgun after reloading when in the middle of the mag (both of which would eject an unused cartridge). It gets especially annoying when I am performing an early reload to save time and end up taking longer than I should. Will Brink's weapons be realistic or just another letdown?
I do find it sorta annoying as well, but something I can overlook.
For the most part, not really. When reloading a weapon with all its ammunition spent, the animation is the same as the animation for reloading early (a new round is not chambered, so no cool lock-and-load scene). Also, when reloading early, an extra bullet is not added to the current ammo count.
I believe that the Mossington will be pumped no matter how many cartridges still remain in the tube.
