Not too bad considering the bloody cold weather it looks like you are shooting in.
Gloves make everything slower so I say good effort all around.
I would have to agree with some comments that a weapon mounted carrier would be much faster for speed reloads, my silly mantra is "on the gun is faster than on the belt" but that can only be applied against certain firearms (ie, I run my carbine with 4 ten round LAR mags coupled together for 40 on the gun. Obviously, I cannot run something like this on a pistol)
Get a copy of Magpuls Dynamic Shotgun. There are tons of little things that can be used/changed/tweaked that just make your loading that much faster. The more techniques you practiced and commit to muscle memory, the more tools you will have in the face of adversity.
As a side note, has anyone else noticed that TV-PressPass looks like a younger Quentin Tarantino?
