25 oz Silver Bullet .20 mm

I was excited to get my 20mm silver bullet and was a little shocked when I opened the package and it looked nothing like the picture. So I looked up what a 20mm cartridge looked like and felt better. It looks like an actual 20mm cartridge, but the picture on this site must be a different caliber.
That didn't affect my rating, though. The reason I only gave it 3 stars is because it had a bunch of dents in it. It was packaged really well and I'm sure the dents were there before shipping, but the first thing everyone says is, "Why does it have all those dents?"
