FX Impact Long Slug Magazine Cover 22CAL 28 RND

I am trying to find some good slugs.  Longer slugs heavier slugs don't fit the standard Sideshot magazine so I made this.  There are probably others here somewhere but I didn't check.  It works on my magazine, but it's a close-fitting part, and I wish I had a few more to see if I needed to be adjusted.  

This cover replaces the clear cover on the 22CAL, 28 Rnd, FX sideshot magazine to allow longer heavier slugs.  It works for sure with 11.5mm long Javelin Gen2 40gr but it should clear up to 12mm.  I added holes at each of the carousel locations so you could see the rounds remaining.
