A while back during a discussion on speed loaders, I commented that I didn't have any trouble loading flat faced wadcutters into my 442 using Comp-I's. At the time, I couldn't get my video to upload, but now I am hoping this will work. I didn't see a way to embed it, so I've linked it below.

Those rounds are my own loads, but factory ammo works the same for me. The gun is wearing LG-405's. Folks with other grips may not have the same results.
