I have never shot anything bigger than say a 300 weatherby mag or 338 mag but I like alot on here got " WRAPPED" the hardest by a Rem 870 slug gun with 3 1/2" mag slugs. It litterely felt like I took a straight right between the eyes. My eyes watered after the shot. What a tooth rattler. It wasn't my gun because it would not have shot those EVER again.
