I would like to suggest to rework the reload animation into something more "creative".
At the moment its just the regulary sniper animation, my suggestion would be to give it some more movement into it, more likely to fit into the kind of WW1/2 weapon behavior.
For perfect example would be like the animation from cod: mw2 of the intervention. (not to copy it 1:1 but the inspire)

I know my english isnt the best, but i hope you get an idea of what i was thinking.
You did a awesome job by designing the weapon :)
