The issue isn’t limited to shotguns as some magazine-fed guns are also concerned. The problem is when you do a partial reload, you systematicaly rechamber a round at the end of the animation even though there is already a round inside the chamber as the weapon wasn’t emptied prior to the reload. This unnecessarily lengthens reloading and is annoying to see especially when considering darkflow just added 2 guns that have this issue.
The weapons concerned are the Sten MK3 (from a premium squad), the Winchester M1912, US Browning Auto 5, japanese Browning Auto-5, Ithaca 37 and Lee-Enfield No. 4 Mk1 (T).
Note that there may be more guns concerned but I dont have all event and premium squad although I tried to test all I could.
And yes it isn’t the first time I make a post about this. Here is a more detailed one of mine talking on the same topic: Fix and improvements on reloads
